Previously, send_notice_message() called queue_message() with NULL pss, causing
all NOTICE messages to fail silently. This affected filter validation errors
(e.g., invalid kinds > 65535 per NIP-01) where clients received no response.
Changes:
- Updated send_notice_message() signature to accept struct per_session_data* pss
- Updated 37 call sites across websockets.c (31) and nip042.c (6)
- Updated forward declarations in main.c, websockets.c, and nip042.c
- Added tests/invalid_kind_test.sh to verify NOTICE responses for invalid filters
Fixes issue where REQ with kinds:[99999] received no response instead of NOTICE.
