per-player connection exists anywhere (#483; the account's "bound identity" is now the derived
`synthetic_owner_identity`, minted by no connection and presented by no client).

A coordinator connection subscribes a base list of literal `SELECT * FROM <table>` queries, plus
the sharded tables when more than one database is configured (`coordinator_queries` in
`connection.rs`). The sharded tables are conditional
because **a subscription to a table the deployed module does not have fails to apply**, which would
fail the whole gateway — so a gateway restarted before a module republish must not ask for the
sharded tables.
A Coordinator subscribes literal table queries and the Relay table declarations in
`gateway/src/stdb/connection.rs`. Multi-database configurations also subscribe the Shard control
tables. A dedicated Realm-core connection omits 30 world catalogues, including creatures, spells,
quests and taxi routes. It retains item catalogues needed by Mail and auctions, faction relationships,
and every dynamic, control and Relay table. If Realm-core also hosts a configured World Shard, it
keeps the full query set. Idle World Shards keep their subscriptions. Reconnect preserves the role.

Publish a Module that contains the required tables before starting this Gateway. An unknown table
causes subscription setup to fail; it does not produce an empty optional cache.
