Refactor and consolidate test suite

- Moved old tests from tests/old/ to main tests/ directory
- Renamed nostr_test_bip32.c to bip32_test.c for consistency
- Renamed nostr_crypto_test.c to crypto_test.c for consistency
- Renamed wss_test.c and moved from old directory
- Fixed unused variable warning in bip32_test.c
- Updated build system and workspace rules
- Cleaned up old compiled test executables
- Updated nostr_common.h and core_relays.c
- Removed obsolete nostr_core.h.old backup file

This consolidates all active tests into the main directory and removes
outdated test files while maintaining a clean, organized structure.

MAKEFILE POLICY: There should be only ONE Makefile in the entire project. All build logic (library, tests, examples, websocket) must be consolidated into the root Makefile. Do not create separate Makefiles in subdirectories as this creates testing inconsistencies where you test with one Makefile but run with another.
TESTS POLICY: On the printout, dont just show pass or fail, show the expected values, and what the actual result was. If dealing with nostr events, print the entire json event. If dealing with relay communication, show the whole communication.
