Table editor import fails to raise identity sequence for tables with uppercase names

When you import rows (CSV upload or spreadsheet paste) into a table that has an identity or serial column, Studio runs a "raise the sequence" step afterwards so the sequence continues above the imported values. That step uses `getUpdateIdentitySequenceSQL` (`packages/pg-meta/src/sql/studio/table-editor/identity.ts`), which builds the first argument to `pg_get_serial_sequence` like this: ``` pg_get_serial_sequence('<schema>.<table>', '<column>') ``` The schema and table are joined without quoting. `pg_get_serial_sequence` reads an unquoted argument as a case-folded identifier, so for a table or schema whose name has uppercase letters (e.g. `Users`, common for people coming from Prisma or TypeORM) it looks for `schema.users` and errors with `relation "..." does not exist`. Two consequences: 1. The import surfaces a database error even though the rows already landed. 2. The sequence is never raised, so it stays at 1. The next insert that relies on the identity/serial default generates 1, 2, 3... which collide with the imported rows and fail with a duplicate primary key. Repro: ```sql create schema "App"; create table "App"."Users" ("Id" bigint generated by default as identity primary key, val text); insert into "App"."Users" ("Id", val) values (5, 'a'), (6, 'b'); -- what the builder currently generates: select pg_get_serial_sequence('App.Users', 'Id'); -- ERROR: relation "app.users" does not exist ``` The same function already quotes the relation correctly in its `FROM` clause, and the sibling `getDuplicateIdentitySequenceSQL` quotes its `::regclass` argument with `ident()`. Only the `pg_get_serial_sequence` argument was left unquoted.
