CI: Standardize imports

[Tabaie]

Adds goimports to code generation and PR checks.

---

Note

Enforces goimports in CI and code generation, standardizing import ordering/aliases across the codebase.

• CI:
  • Add goimports check to /.github/workflows/pr.yml and /.github/workflows/push.yml.
• Code generation:
  • Run goimports in internal/generator/main.go after formatting steps.
• Repo-wide imports:
  • Normalize import ordering and add aliases per goimports across many files (no logic changes).

ok 👍 since now we are at go 1.24+ may be worth to add this as tool ( https://go.dev/ref/mod#go-mod-file-tool ) . same for asmfmt etc.
