Switch date_last_updated from valid_from (rate change time) to
last_verified_at (last check time). All dates verified in the same daily
run now show a consistent timestamp rather than varying by when rates
last changed. Also commit per-date instead of batching 10 days — prevents
a single API error from rolling back up to 9 preceding committed dates.

- schema defined gross_rate/net_rate but every query (fetch job,
bookability, competitors) uses rate_gross/rate_net — rename the
columns, with an idempotent DO-block migration for existing tables
- roll back the session when a date fails so one bad statement no
longer poisons the whole sync run (every subsequent write was dying
with 'current transaction is aborted')
