Add User Hash and Media Path Repair Command

[LoicBonavent]

Summary

• Add check_user_hashes to detect and repair inconsistencies caused by accidental SECRET_KEY changes or username changes.
• Support read-only checks with --dry, repeatable profile selection with --username, and filtering to video owners with --with-videos.
• Rename or merge media directories without overwriting different files, and update matching database file paths and profile hashes.
• Resolve verified encoding/transcription report collisions while preserving transcription artifacts.
• Repair each profile independently: conflicts block only the affected profile, while valid profiles continue.
• Roll back the affected profile’s database changes and file moves on failure; stop on database, filesystem or rollback errors.
• Add grouped, colored reports distinguishing unchanged, repaired, blocked and unprocessed profiles, with a nonzero exit status when conflicts remain.
• Add regression tests for dry runs, file references, directory merges, partial success, concurrent changes, report archiving and rollback behavior.

Validation

• Activate the project environment with workon django_pod4.
• Flake8 passes for the command and its tests.
• All 48 tests pass in pod.video.tests.test_check_user_hashes, using pod.main.test_settings with an isolated SQLite test database and temporary media directories.
• Tests cover Podfile documents and images, absolute paths, interrupted moves, concurrent changes, partial repairs, transcription report collisions, missing tasks, symlinks and unsupported storage.
