fix: remove all tk script references — fix CI failures

Remove deprecated tk wrapper and all associated test files, helper
scripts, and references. The v3 event-sourced ticket system (ticket CLI)
replaces all tk functionality.

- Delete 18 tk test files and 3 tk helper scripts
- Remove tk allowlist from tickets-tracker bash guard hook
- Update scripts that called tk sync to use ticket commands
- Remove require-tk.sh sourcing from validate-issues.sh
- Clean up tk references in shim/setup/probe test files
