hzhang 03b89a547c fix(db,topics): time.Time params for TIMESTAMP + comment-aware SQL split
Two fixes surfaced by sim e2e test (which otherwise passed full
lifecycle: created → signup_open → 3 signups → allocator → debating
→ arguments → verdict gate (409 early, 201 after debate_end_at) →
completed).

1) MySQL TIMESTAMP rejects RFC3339-with-Z strings — passing those as
   sqlx parameters fails with "Incorrect datetime value". Changed
   CreateTopicInput lifecycle fields from string to time.Time; the
   handler parses+UTCs in validateLifecycleTimes (which now returns
   the parsed array along with the validation result) and passes
   time.Time to the store. The mysql driver formats correctly.

2) splitSQL was naive `strings.Split(s, ";")` which split inside
   comments — the 001 migration had a few `--` lines containing `;`
   ("signup_close_at; immutable", etc) which broke. Migration text
   tidied to not use `;` inside comments, AND splitSQL upgraded to
   skip both `-- ...` and `/* ... */` comment regions before splitting.

Sim verified — clean apply on fresh MySQL.
