## Summary
- Replaces all `depot-ubuntu-24.04` runners with `ubuntu-latest`
- Replaces all `depot-ubuntu-24.04-8` runners with
`ubuntu-latest-8-cores`
- Updates storybook build cache keys in ci-front.yaml to reflect the
runner name change
Reverts the temporary Depot migration introduced in #18163 / #18179
across all 23 workflow files.
## Summary
- Replace all `depot-ubuntu-24.04-8` runner references with the
equivalent GitHub-hosted `ubuntu-latest-8-cores` runner
- Updated across 4 workflow files: `ci-front.yaml`, `ci-server.yaml`,
`ci-emails.yaml`, `ci-sdk.yaml`
- Also updated cache key names in `ci-front.yaml` that referenced the
depot runner name
## Test plan
- [ ] Verify CI workflows run successfully on the new GitHub-hosted
larger runners
- [ ] Confirm cache keys work correctly with the updated naming

## Problem
The concurrency rules in CI workflows were cancelling in-progress test
runs even on the main branch. This caused inconsistent check counts when
multiple commits were pushed in quick succession.
## Solution
Updated `cancel-in-progress` in all CI workflows to be conditional:
- **On main branch**: Tests run to completion (no cancellation)
- **On feature branches**: Tests are cancelled when new commits are
pushed (saves CI resources)
## Changes
Modified 11 workflow files to use:
```yaml
cancel-in-progress: ${{ github.ref != 'refs/heads/main' }}
```
This ensures every commit to main gets fully tested while maintaining
efficiency on feature branches.
