fix(metrics): make minute/second date ranges resolve — and roll from now

[DanielVisca]

Found by: metrics push-model dogfood validation (first-time-user pass over the new SDK-push pipeline; reported symptom: viewer shows "No data" for last 5/30 minutes while storage has fresh rows).

Problem

Picking Last 5 minutes or Last 30 minutes in the metrics viewer renders "No data" even when the metric has samples seconds old (verified: 5,070 rows in the window in ClickHouse while the UI showed nothing). Two stacked defects in lib/utils/dateFilters:

1. isStringDateRegex accepts [hdwmqy] only, but dateOptionsMap defines M (minute) and s (second). The viewer's minute options emit -5M/-30M → regex miss → dateStringToDayJs returns null → the viewer's resolveDate falls back to dayjs('-30M') (invalid) → the loader silently returns [].
2. Even parsing wouldn't have made them correct: dateStringToDayJs anchors every relative date at startOf('day'), so -30M would mean today 00:00 − 30 min = yesterday 23:30 — a ~24h window labeled "Last 30 minutes". This also means the working -1h option has been querying since yesterday 23:00 while labeled "Last 1 hour".

Changes

• Regex unit class gains M and s (both already in dateOptionsMap and componentsToDayJs — the regex was the only gap).
• Sub-day units (hour/minute/second) anchor at now (rolling window), matching the backend's relative_date_parse; calendar units (d/w/m/q/y) keep startOf('day') anchoring so insights behavior is untouched.

How did you test this code?

• New frozen-time test locks both behaviors (-30M/-5M/-1h/-45s resolve to exact rolling instants). Red without the fix (1 failed / 39 passed), green with it (40/40) — the 39 pre-existing cases pin calendar-unit anchoring unchanged.
• Empirical cross-check: the same window that renders "No data" in the viewer returns 21 per-minute points via query-metrics — confirming data presence and isolating the bug to date resolution.

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

• Part of the commissioned metrics-validation dogfood (DRI @DanielVisca): act as a first-time user of the push-model metrics product, chase every discrepancy to root cause, ship observed fixes.
• Note for reviewers outside metrics: this touches the shared date helper; the deliberate scope decision is that only sub-day units change semantics (previously either broken or nonsensically day-anchored), calendar units are pinned by existing tests.

Diff itself is low-risk (regex/anchor fix with a matching test), but greptile-apps[bot] shows an in-progress review (👀) on this PR — should wait for that to finish before auto-approving.

Fixes a real bug in shared date-parsing logic used across many scenes (date filters, app metrics, billing, audit logs) — correct-looking and tested, but no human/agent reviewer has approved or commented on this diff, only weak bot reactions.

This changes shared date-parsing logic (dateStringToDayJs) used across the app for relative date ranges; behavior change is plausible and well-tested, but no independent reviewer has approved the current head — only bot reactions, no substantive review.
