Refactor fragile SQLite regex rewrites into driver-aware query methods

Browse Source 
Move the ON DUPLICATE KEY UPDATE and UPDATE...AS alias SQL rewrites out
of Database::rewriteForSQLite() and into Tag::createNew() and
Tag::recount() as driver-aware branches via a new Database::getDriver()
method. This keeps dialect-specific SQL explicit at the call site rather
than buried in fragile regex transforms.

Also fix Tag::getAlbums() and Tag::getPeople() failing on SQLite when
id_parent is NULL by adding an IS NULL fallback for root-level queries.
