## 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.
