feat: enable feedback button on nightly releases (#8220)

## Summary

Enables the feedback button on nightly releases to collect user feedback
and distinguish it from stable releases in Zendesk.

## Changes

- Add distribution tracking to feedback URL (cloud/nightly/stable)
- Export `getDistribution()` and `ZENDESK_FIELDS` from support config
for reuse
- Enable feedback button for both cloud and nightly builds
- Track distribution in Zendesk as: `ccloud`, `oss-nightly`, or `oss`
- Fix type signatures for `normalizeIndustry`/`normalizeUseCase` to
accept `unknown`

## Requirements

- [ ] Support team needs to add `oss-nightly` as a valid value for the
distribution field in Zendesk

## Test plan

- [ ] Build and run nightly version, verify feedback button appears
- [ ] Click feedback button, verify Zendesk form opens with correct
distribution parameter
- [ ] Verify cloud builds still show feedback button as before
- [ ] Verify stable OSS builds don't show feedback button
