ci: refactor Gitea workflows to use environment variables for workspace paths

- Added WORKSPACE env variable to all workflow jobs
- Changed hardcoded workspace paths to use ${{ env.WORKSPACE }}
- Added pull_request path filters to blockchain-sync-verification.yml
- Updated cross-chain-tests.yml path filters to apps/blockchain-node/** and scripts/multi-node/**
- Removed ait-devnet from default chains in cross-chain-tests.yml
- Disabled test-cross-chain-bridge job (test file not implemented)
- Removed test-cross-chain-bridge from aggregate
