71ee0163de qt: 30.0rc3 translations update (Hennadii Stepanov)
Pull request description:
This PR updates the Polish (pl) translation and addresses [this](https://github.com/bitcoin/bitcoin/pull/33275#issuecomment-3329617679) comment.
Updates for other languages have been skipped, as I believe the review effort would not be worthwhile at this stage of the release process.

QT translations are optional, but the script would error when
'translations_dir' falls back to its default value NULL.
This PR fixes it by moving the set-up of QT translations under
the check for 'translations_dir' presence.

Not enforcing TRUC topology on reorg was the intended
behavior, but the appropriate bypass argument was not
checked.
This mistake means we could potentially invalidate a long
chain of perfectly incentive-compatible transactions that
were made historically, including subsequent non-TRUC
transactions, all of which may have been very high feerate.
Lastly, it wastes CPU cycles doing topology checks since
this behavior cannot actually enforce the topology in
general for the reorg setting.

Using bypass_limits=true is essentially fuzzing part of a
reorg only, and results in TRUC invariants unable to be
checked. Remove most instances of bypassing limits, leaving
one harness able to do so.

A target field was added to the getblock and getblockheader RPC calls in bitcoin#31583, but it mistakingly always used the tip value.
Because regtest does not have difficulty adjustment, a test is added for mainnet instead.
Github-Pull: #33446
Rebased-From: bf7996cbc3
The next commit requires an additional mainnet block which changes the difficulty.
Also fix a few minor mistakes in the test (suite):
- rename the create_coinbase retarger_period argument to halving_period. Before bitcoin#31583 this was hardcoded for regtest where these values are the same.
- drop unused fees argument from mine helper
Finally the CPU miner instructions for generating the alternative mainnet chain are expanded.

`bitcoin-wallet` as-is is merely an offline wallet inspection tool
(introduced more than 9 years ago in PR #13926) that doesn't have any
relation with IPC/multiprocess, so remove it from the list of binaries
that use `libbitcoin_ipc`.

Oversized allocations can cause out-of-memory errors or [heavy swapping](https://github.com/getumbrel/umbrel-os/issues/64#issuecomment-663637321), [grinding the system to a halt](https://x.com/murchandamus/status/1964432335849607224).
`LogOversizedDbCache()` now emits a startup warning if the configured `-dbcache` exceeds a cap derived from system RAM, using the same parsing/clamping as cache sizing via CalculateDbCacheBytes(). This isn't meant as a recommended setting, rather a likely upper limit.
Note that we're not modifying the set value, just issuing a warning.
Also note that the 75% calculation is rounded for the last two numbers since we have to divide first before multiplying, otherwise we wouldn't stay inside size_t on 32-bit systems - and this was simpler than casting back and forth.
We could have chosen the remaining free memory for the warning (e.g. warn if free memory is less than 1 GiB), but this is just a heuristic, we assumed that on systems with a lot of memory, other processes are also running, while memory constrained ones run only Core.
If total RAM < 2 GiB, cap is `DEFAULT_DB_CACHE` (`450 MiB`), otherwise it's 75% of total RAM.
The threshold is chosen to be close to values commonly used in [raspiblitz](https://github.com/raspiblitz/raspiblitz/blob/dev/home.admin/_provision.setup.sh#L98-L115) for common setups:
| Total RAM | `dbcache` (MiB) | raspiblitz % | proposed cap (MiB) |
|----------:|----------------:|-------------:|-------------------:|
| 1 GiB | 512 | 50.0% | 450* |
| 2 GiB | 1536 | 75.0% | 1536 |
| 4 GiB | 2560 | 62.5% | 3072 |
| 8 GiB | 4096 | 50.0% | 6144 |
| 16 GiB | 4096 | 25.0% | 12288 |
| 32 GiB | 4096 | 12.5% | 24576 |
[Umbrel issues](https://github.com/getumbrel/umbrel-os/issues/64#issuecomment-663816367) also mention 75% being the upper limit.
Starting `bitcoind` on an 8 GiB rpi4b with a dbcache of 7 GiB:
> ./build/bin/bitcoind -dbcache=7000
warns now as follows:
```
2025-09-07T17:24:29Z [warning] A 7000 MiB dbcache may be too large for a system memory of only 7800 MiB.
2025-09-07T17:24:29Z Cache configuration:
2025-09-07T17:24:29Z * Using 2.0 MiB for block index database
2025-09-07T17:24:29Z * Using 8.0 MiB for chain state database
2025-09-07T17:24:29Z * Using 6990.0 MiB for in-memory UTXO set (plus up to 286.1 MiB of unused mempool space)
```
Besides the [godbolt](https://godbolt.org/z/EPsaE3xTj) reproducers for the new total memory method, we also tested the warnings manually on:
- [x] Apple M4 Max, macOS 15.6.1
- [x] Intel Core i9-9900K, Ubuntu 24.04.2 LTS
- [x] Raspberry Pi 4 Model B, Armbian Linux 6.12.22-current-bcm2711
- [x] Intel Xeon x64, Windows 11 Home Version 24H2, OS Build 26100.4351

Added a minimal system helper to query total physical RAM on [Linux/macOS/Windows](https://stackoverflow.com/a/2513561) (on other platforms we just return an empty optional).
The added test checks if the value is roughly correct by checking if the CI platforms are returning any value and if the value is at least 1 GiB and not more than 10 TiB.
The max value is only validated on 64 bits, since it's not unreasonable for 32 bits to have max memory, but on 64 bits it's likely an error.
https://learn.microsoft.com/en-us/windows/win32/api/sysinfoapi/ns-sysinfoapi-memorystatusex
> ullTotalPhys The amount of actual physical memory, in bytes.
https://man7.org/linux/man-pages/man3/sysconf.3.html:
> _SC_PHYS_PAGES The number of pages of physical memory. Note that it is possible for the product of this value and the value of _SC_PAGESIZE to overflow.
> _SC_PAGESIZE Size of a page in bytes. Must not be less than 1.

Prior releases installed using these paths. Especially annoying was that the lingering registry entry for the uninstaller would show up as "Bitcoin Core (64-bit)" besides the current "Bitcoin Core" entry in the list of installed programs, and whichever was uninstalled last would fail to work as they would default to the same install directory.

In the presence of smaller transactions on the network, blocks can sustain a
higher relay rate than 7tx/second. In this event, the per-peer inventory queues
can grow too large.
This commit bumps the rate up to 14 tx/s (for inbound peers), increasing the
safety margin by a factor of 2.
Outbound peers continue to receive relayed transactions at 2.5x the rate of
inbound peers, for a rate of 35tx/second.

m_cached_from_me is used to track whether a transaction is "from me", i.e. has
any inputs which belong to the wallet. This is held in memory only in
the same way that a transaction's balances are.

Rebased-From: 113a422822
Instead of checking whether the total amount of inputs known by the
wallet is greater than 0, we should be checking for whether the input is
known by the wallet. This enables us to determine whether a transaction
spends an of output with an amount of 0, which is necessary for marking
0-value dust outputs as spent.

If something is imported into the wallet, it can change the 'from me'
status of a transaction. This status is only visible through
gettransaction's "fee" field which is only shown for transactions that
are 'from me'.
