feat: add Gitea Actions CI for make check (closes #96)

- Add .gitea/workflows/check.yml running make check on PRs and pushes to main
- Fix .golangci.yml for golangci-lint v2 config format (was using v1 keys)
- Migrate linters-settings to linters.settings, remove deprecated exclude-use-default
- Exclude gosec false positives (G117, G703, G704, G705) with documented rationale
- Increase lll line-length from 88 to 120 (88 was too restrictive for idiomatic Go)
- Increase dupl threshold from 100 to 150 (similar CRUD handlers are intentional)
- Fix funcorder: move RemoveImage before unexported methods in docker/client.go
- Fix wsl_v5: add required blank line in deploy.go
- Fix revive unused-parameter in export_test.go
- Fix gosec G306: tighten test file permissions to 0600
- Add html.EscapeString for log output, filepath.Clean for log path
- Remove stale //nolint:funlen directives no longer needed with v2 config
