## Summary
- Refactored `evaluateDateFilter` in the workflow filter action from
native `Date` to the Temporal API, using the shared
`parseToInstantOrThrow` and `isSamePlainDate` utilities from
`twenty-shared` (resolving the long-standing `// TODO: refactor this
with Temporal`).
- Fixed a bug in the `IS` operand: it previously compared only
`getDate()` (day-of-month 1–31), so e.g. `2023-01-15` incorrectly
matched `2023-02-15`. It now compares the full calendar day in UTC.
- Removed server-local-timezone leakage: `IS_TODAY` and day comparisons
now run in UTC (consistent with the neighbouring relative-date filter
util), instead of relying on `toDateString()`/`getDate()`.
## Behavior changes (intended)
- `IS` now matches on the full UTC calendar day, not day-of-month.
- `DATE_TIME` `IS` matches on the same UTC day (not exact-instant
equality).
- Date comparisons are UTC-based, so evaluations near midnight in a
non-UTC server locale may differ from the old local-timezone behavior.
- Parsing is stricter (ISO + known formats via `parseToInstantOrThrow`);
malformed operands resolve to "no match" instead of being loosely
guessed by `new Date()`.
