Filenames with slashes in volume filtering

[yannik131]

Closes #1123

[Copilot]

Pull request overview

This PR fixes volume filename filtering for files whose names begin with / (e.g., remote videos), which previously caused routing/errors when the filename pattern contained a leading slash (issue #1123).

Changes:

• Allow the filename filter route parameter to include slashes by widening the route constraint.
• URL-encode filename patterns on the frontend before sending them as a path parameter.
• Decode percent-encoded filename patterns in the API controller, and extend test coverage for slash/encoding edge cases.

Why this if it matches anything?

After additional investigation:

• Laravel and vue already encode/decode URI components
• However, laravel decodes the route parameters and throws an exception if the decoded pattern contains invalid characters such as slashes
• 2 possible fixes:
  • encode/decode manually on top of vue/laravel encoding/decoding, then laravel can't "see" the invalid characters after decoding the pattern just once
  • add the ->where('pattern', '.*'); to explicitly allow any characters, including slashes

The second approach is actually cleaner so I'll remove the manual encoding/decoding
