Review Comment:
Mode 2 invalidation needs to use the canonical local key, not the raw
request/log name. `dropDbImpl()` resolves a request like `drop database
mixeddb` to the hot `MixedDb` object and drops `dorisDb.getRemoteName()`, but
`ExternalMetadataOps.dropDb()` then calls `afterDropDb(dbName)` and the edit
log stores that original `dbName`. Here `invalidateDatabaseCache("mixeddb")`
removes from `databaseNames`, `databases`, and `dbIdToName` by exact key, while
mode 2 stores the preserved `MixedDb` key. The stale names/object/id entries
remain hot, so `getDbNullable("mixeddb")` can resolve through the old
`NameCacheValue` and return the dropped DB without reloading. Please
canonicalize against the hot name/object cache, or log/pass
`dorisDb.getFullName()`, before invalidating.

Review Comment:
Same key mismatch on the table path for replay/rename: this can find the
canonical object but then invalidate the raw spelling. In mode 2,
`getTableForReplay("foo")` can resolve the hot `Foo` object via
`NameCacheValue`, but `localTableName` stays `"foo"` because
`toLocalTableName()` preserves its input. `invalidateTableCache("foo")` then
misses the `tableNames`, `tables`, and `tableIdToName` entries keyed by
`"Foo"`. Leader `DROP TABLE` uses `dorisTable.getName()` in the callback, but
the edit log records the user spelling and `replayDropTable()`/rename replay
pass that raw name here, so the old table can remain visible. Use the resolved
`dorisTable.getName()` or another canonical hot key for invalidation.
