Extends the existing timelog (used by S1/S2 battle tests) with:
- state: running / paused / stopped / reconciled (default running)
- last_paused_at + total_paused_seconds (drives accrued compute)
- accrued_seconds (compute, depends date_started/_finished/paused)
- billed_hrs/min/sec + billed_total_seconds + billed_pct (compute)
- product_id (split-by-product reconciliation per screen 10)
- notes
- job_id (related, indexed — for fp.job.active_timer_ids O2M)
Field naming follows the existing date_started / date_finished
convention (NOT started_at / stopped_at as my plan said — adjusted
inline to match what's already in the file).
The existing battle tests use the timelog without state — default
'running' so they're unaffected. State only flips when Sub 12b's
Stop Timer dialog commits.
