fix(db,combo): clear the NEW base-reds the 08-06 merge batch introduced

The tip moved while the first sweep PR (#9600) was in review, and three fresh
base-reds landed with it — same classes as before, all reproduced on the pure
tip 9995bc4893:

1. ANOTHER migration collision: #9061 shipped 134_ccr_blocks.sql onto the slot
   134_proxy_logs_egress_ip.sql (#9291) has held since 08-04. getMigrationFiles()
   throws on collision, so every DB-touching test died at bootstrap again.
   Renumbered to 139 (next free slot). No retroactive guard needed this time:
   both statements are IF NOT EXISTS, and no DB can have applied it as 134 —
   the runner refused to run at all while the collision existed.
2. BROKEN IMPORT killing the combo module graph: #8894 imported
   preferAntigravityConnectionsWithStoredProject from
   ../antigravityProjectPersistence.ts — a module that exists NOWHERE in the
   repo (it came from an unmerged sibling branch). Anything importing
   quotaStrategies.ts died with ERR_MODULE_NOT_FOUND. Implemented the helper in
   the real persistence module (antigravityProjectPersist.ts, #8491) with the
   semantics the call site needs — prefer connections that already carry a
   stored projectId, never emptying the pool — and pointed the import there.
   New regression suite tests/unit/antigravity-prefer-stored-project.test.ts
   (5/5), including an import-graph probe that reproduces the break shape.
3. Sibling-test drift from #9106 (gemini-3.1-pro-high now user-callable): its
   own suites were updated but provider-models-route.test.ts was not. Expected
   discovery list realigned; testFrozen 1784->1787 justified in the baseline
   (irreducible +2 after comment compression; gate counts split-newlines).

Also regenerated tests/snapshots/provider/translate-path.json — addition-only:
devin-cli-agentic, raycast, regolo (today's provider merges), zero removals.

image-generation-route 20/20 (was import-dead), provider-models-route 59/59,
antigravity-prefer-stored-project 5/5, provider-translate-path-golden 3/3.
