Fix SeaweedFS S3 bucket extended attributes handling (#7854)

* refactor: Convert versioning to three-state string model matching AWS S3

- Change VersioningEnabled bool to VersioningStatus string in S3Bucket struct
- Add GetVersioningStatus() function returning empty string (never enabled), 'Enabled', or 'Suspended'
- Update StoreVersioningInExtended() to delete key instead of setting 'Suspended'
- Ensures Admin UI and S3 API use consistent versioning state representation

* fix: Add validation for bucket quota and Object Lock configuration

- Prevent buckets with quota enabled but size=0 (validation check)
- Fix Object Lock mode handling to only pass mode when setDefaultRetention is true
- Ensures proper extended attribute storage for Object Lock configuration
- Matches AWS S3 behavior for Object Lock setup

* feat: Handle versioned objects in bucket details view

- Recognize .versions directories as versioned objects in listBucketObjects()
- Extract size and mtime from extended attribute metadata (ExtLatestVersionSizeKey, ExtLatestVersionMtimeKey)
- Add length validation (8 bytes) before parsing extended attribute byte arrays
- Update GetBucketDetails() and GetS3Buckets() to use new GetVersioningStatus()
- Properly display versioned objects without .versions suffix in bucket details

* ui: Update bucket management UI to show three-state versioning and Object Lock

- Change versioning display from binary (Enabled/Disabled) to three-state (Not configured/Enabled/Suspended)
- Update Object Lock display to show 'Not configured' instead of 'Disabled'
- Fix bucket details modal to use bucket.versioning_status instead of bucket.versioning_enabled
- Update displayBucketDetails() JavaScript to handle three versioning states

* chore: Regenerate template code for bucket UI changes

- Generated from updated s3_buckets.templ
- Reflects three-state versioning and Object Lock UI improvements
