feat: migrate from MySQL to Postgres with pgschema

Browse Source 
Replace MySQL 8.0 with Postgres 17 across the entire stack:

- Add declarative schema/schema.sql for pgschema (merged from 21 migrations)
- Delete migrations/ directory (sqlx migrations no longer used)
- Update all sprout-db queries: positional $N params, ON CONFLICT,
  string_agg, array_position, encode(), pg_catalog partitions
- Update sprout-audit: pg_advisory_lock replaces GET_LOCK
- Update docker-compose, .env.example, justfile, CI, and scripts
- Cargo.toml: sqlx mysql feature → postgres
