chore: fix formatting and lint errors across Makefile, backend, and adminfront

This commit addresses several linting and formatting issues that caused CI checks to fail:
- Makefile: Removed obsolete '--organize-imports-enabled' from Biome and switched to '@biomejs/biome'.
- backend: Fixed spacing and alignment issues according to gofmt.
- adminfront: Fixed multiple unused variables and imports, and configured unsafe fixes in the Biome config to remove dead code.
