Remove woodpecker module and fix branch protection dependency

- Remove woodpecker_repository module and provider (repos managed outside TF)
- Add removed block with destroy=false to drop state without destroying
- Add module.team to branch_protection depends_on to prevent race condition
- Add lifecycle ignore_changes for team permission (provider bug: API returns
  "none" but rejects it on write)
