fix(workflows): proper secret validation and dependabot support

**Claude Code Review workflow:**
- Check secret at job level: skip entire workflow if CLAUDE_CODE_OAUTH_TOKEN is not set
- Remove unnecessary steps checking secret in bash (doesn't work reliably)
- Add comprehensive header documentation explaining optional setup
- Workflow now gracefully skips when secret is missing

**dev-to-main workflow:**
- Fix dependabot branch validation using regex (=~) instead of glob (==)
- Pattern ^dependabot/ now correctly matches branches like dependabot/github_actions/*
- Add detailed logging when dependabot PR is detected
- Both actor check and branch prefix check working properly

**Result:**
- Dependabot PRs will now pass validation without needing dev branch
- Claude Code Review won't fail when secret is missing (just skips)
- All PR checks should pass for dependency update PRs

Fixes GitHub Actions errors for dependabot PRs.
