Add PostHog as a telemetry provider for cloud builds so custom events
can be correlated with session recordings. Follows the same pattern as
MixpanelTelemetryProvider with dynamic import, event queuing, and
disabled events from remote config. Tree-shaken away in OSS builds.
The posthog-js package uses Apache-2.0 (verified from its LICENSE file)
but declares it as "SEE LICENSE IN LICENSE" in package.json, which
the license checker can't parse.

## Summary
Adds CI workflow to validate OSS build compliance by checking for
proprietary fonts and non-approved dependency licenses.
## Context
- Part of comprehensive OSS compliance effort (split from closed PR
#6777)
- Uses simple bash/grep approach following proven #8623 pattern
- Complements telemetry checking in PR #8826 and existing #8354
## Implementation
### Font Validation
- Scans dist/ for proprietary ABCROM fonts (.woff, .woff2, .ttf, .otf)
- Fails if any ABCROM fonts found in OSS builds
- Provides clear fix instructions
### License Validation
- Uses `license-checker` npm package
- Validates all production dependencies
- Only allows OSI-approved licenses:
- MIT, Apache-2.0, BSD-2-Clause, BSD-3-Clause, ISC
- 0BSD, BlueOak-1.0.0, Python-2.0, CC0-1.0
- Unlicense, CC-BY-4.0, CC-BY-3.0
- Common dual-license combinations
### Workflow Details
- Two separate jobs for parallel execution
- Runs on PRs and pushes to main/dev
- Builds with `DISTRIBUTION=localhost` for OSS mode
- Clear error messages with remediation steps
## Testing
- [ ] Font check passes on current main (no ABCROM fonts in dist)
- [ ] License check passes on current main (all approved licenses)
- [ ] Intentional violation testing
## Related
- Supersedes remaining parts of closed PR #6777
- Complements PR #8826 (Mixpanel telemetry)
- Follows pattern from PR #8623 (simple bash/grep)
