Address review: fix NULL asymmetry in backend sync decisions (PR #5511 )

- BackendSyncDecision.cpp: treat asymmetric NULLs as mismatches
  (client=NULL + backend="bob" → SYNC_USER, not SYNC_NONE)
- Tests: replace weak null assertions (a >= 0 always true) with
  specific checks for SYNC_USER/SYNC_SCHEMA on asymmetric NULLs,
  both-null → no sync, schema asymmetric null (+2 tests, plan 15→17)

Extract backend variable sync decisions (Phase 3.6, #5494 )

New: include/BackendSyncDecision.h, lib/BackendSyncDecision.cpp

determine_backend_sync_actions() returns bitmask of needed sync:
- SYNC_USER: username mismatch → CHANGE USER required
- SYNC_SCHEMA: schema mismatch → USE <db> required (skipped if
  SYNC_USER set, since CHANGE USER handles schema)
- SYNC_AUTOCOMMIT: autocommit state mismatch

Covers both MySQL (7 verify functions) and PgSQL (2 verify functions)
at the decision level — the core comparisons are the same.
