maziggy 9e7f6cafd9 fix(backup): preserve NOT NULL/DEFAULT/FK/UNIQUE in Postgres→SQLite backup (#2526) ...

On a PostgreSQL install, create_backup_zip() exports a portable SQLite copy
so backups move between engines. It rebuilt each table with only column name
+ type + PK, dropping NOT NULL, server_default/DEFAULT, foreign keys, and
unique constraints. Restore onto SQLite page-copies that schema straight onto
the live database, and post-restore init_db() can't repair it (create_all is
CREATE TABLE IF NOT EXISTS). So server_default columns like
spoolbuddy_devices.created_at (server_default=func.now()) ended up with no
DEFAULT: SQLAlchemy omits them on INSERT, the DB wrote NULL, and the next read
500'd on Pydantic validation. Every server_default column was exposed the same
way; the FK/unique loss followed from the same simplified CREATE TABLE.

Build the portable schema with Base.metadata.create_all() against a SQLite
engine instead of the hand-rolled loop, so it emits the exact DDL a native
SQLite install gets (NOT NULL, DEFAULT func.now() -> CURRENT_TIMESTAMP, FKs,
unique constraints, indexes). The data-export insert path is unchanged, and
the #1333 OIDC-icon guard is preserved automatically (LargeBinary -> BLOB),
which lets the now-redundant _sqlalchemy_type_to_sqlite_type() helper be
removed. Fixes newly-created backups; a backup from an older build still
carries the degraded schema, so re-take backups after upgrading.

Replace the #1333 type-mapping unit tests with three that inspect the real
backup schema via metadata.create_all + PRAGMA table_info: icon_data is BLOB,
created_at keeps its CURRENT_TIMESTAMP DEFAULT, a NOT NULL non-PK column stays
NOT NULL.
