fix: pin golangci-lint install to commit SHA (fixes #13)

- Fix Dockerfile: use correct v2 module path with commit SHA
  (github.com/golangci/golangci-lint/v2/cmd/golangci-lint@eabc2638...)
- Add CGO_ENABLED=0 for alpine compatibility
- Fix 35 lint issues found by golangci-lint v2.1.6:
  - Remove unused nolint directives, add nolintlint where needed
  - Pre-allocate migrations slice
  - Use t.Context() instead of context.Background() in tests
  - Fix blank lines between comments and exported functions in ui.go
