CC1 audit fixes #6/#8/#9 from CONSOLIDATED.md

#9 sportas trailing-slash (verified clean):
  Frontend constructs /sportas/{id}/profil cleanly (sport2.html:L1582).
  Live test: 200 on /sportas/449/profil; 307 on trailing-slash variant
  (FastAPI auto-redirect, harmless). No fix needed.

#8 [VERIFY]/[UNRESOLVED] klubovi surfaced to audit log:
  3 manual_review klubovi (2619 Čavle, 2630 Opatija, 4426 empty) inserted
  into pgz_sport.sys_audit with action='klub.manual_review_pending',
  visible in /audit page for human triage. Total audit rows: 633.

#6 backup-table archival:
  Moved 26 *_backup_*/*_premerge_*/*_pre_*/*_dedup_*/*_deprecated_*/*_garbage_*
  tables (~97k rows) from pgz_sport → pgz_sport_archive schema.
  - Snapshot dump: _audit/db_snapshots/backup_tables_20260505_085057.sql.gz (56 MB)
  - Script: scripts/archive_backup_tables.sql (idempotent, with rollback)
  - pgz_sport canonical tables: 112 → 86
  - All live API endpoints still 200, db=ok, errors_logged stable at 23
  - Josip Zec test 257/182/15 still PASS

.gitignore: exclude _audit/db_snapshots/ (large pg_dump archives)

+-- archive_backup_tables.sql — moved 26 backup/snapshot tables out of pgz_sport
+-- Author: cc1@rinet.one  Date: 2026-05-05
+-- Re-runnable (idempotent — only moves tables that still match pattern in pgz_sport)

+--   ~97k rows of stale data archived (no DROP — recoverable via ALTER ... SET SCHEMA back)
