## Summary
Upgrades the dashboard form layer from `@conform-to` 0.9 to 1.x. No
behaviour change is intended; this is the conform API migration only.
conform 1.x peer-depends on `zod` `^3.21 || ^4`, so it runs on the
current zod 3 and is a prerequisite for upgrading the repo to zod 4:
conform 0.9 imports `ZodNativeEnum`, `ZodEffects`, and `ZodPipeline`,
all removed in zod 4, so the webapp cannot build against zod 4 until
conform is on 1.x. Landing this first (on zod 3) keeps the zod 4 PR
focused on zod alone.
## Testing
Did a bunch of local smoke tests and E2E playwright tests, several
rounds of different reviewers, all clean.
## What this does
Polish + bug-fix pass on the Errors page so it can ship to everyone.
Touches the Slack alert config UX, errors list, error detail page, and
unhides the SideMenu entry for non-admins.
## Decisions
**"No channel" item over standalone Remove button**
Chose pinning a `<XMarkIcon /> No channel` `SelectItem` above the
channel list. Rejected the standalone "Remove channel" link in a
`<Hint>` — color/hover behaviour clashed with the sibling `<TextLink>`,
and "channel selection" is the right context for clearing. Server action
already deletes the channel when `slackChannel=""` is submitted.
**Slack `<!date^>` token over per-user TZ field for alerts**
Chose Slack's native `<!date^TS^…>` token so each viewer sees timestamps
in their own timezone (UTC fallback). Rejected per-user/per-org TZ
schema work — works for multi-region channels for free. Email/dashboard
TZ source-of-truth filed as TRI-8885 / TRI-8886.
**Make errors GA**
- Added versions filtering on the Errors list and page
- Added errors stacked bars to the graph on the individual error page
