fix: await transaction commit and preserve finalized handles

[ospfranco]

Continuation on top of #455

• Dedups transactions tests on queries.ts
• makes commit sync, like rollback
• Fires the flush pending queries call and DO NOT await for it's result, to avoid locking the transaction finish. Reactive queries should still run in the background without interfering with the current transaction that is just closing
• Moves from biome to oxc and tsgo with type aware rules
