build(server): hold SQLite-only SQL spellings to a shrinking baseline

ESLint keeps raw SQL out of the repositories, but nothing looked at the rest
of src/: the entities, the domain services, the src/db lifecycle files or a
migration added from now on. scripts/dialect-lint.mjs (npm run lint:dialect)
reads every string and template literal under src/, skipping comments, and
counts INSERT OR IGNORE/REPLACE, datetime(), strftime, json_extract, GLOB,
last_insert_rowid, AUTOINCREMENT, PRAGMA outside the lifecycle files, ||
concatenation in SQL and .insertId reads. scripts/dialect-baseline.json
holds today's thirteen hits; the counts may only go down, like lint:size.
The dialect layer is not scanned, and neither are the migrations that have
shipped.

The four seeders that still spelled INSERT OR IGNORE (addons, photo and
document providers, the schema_version marker) are Kysely inserts that do
nothing on conflict now, so a re-run still leaves an operator's rows alone.
They leave the SQL-string exemption list in eslint.config.mjs and their pins
in the selector test.
