Xvideos: harden fragment ID extraction and fallback

[smegmarip]

Changes:

• Add numeric-leading JDownloader filename rule: ^([0-9]{6,11})_.+ -> $1.
• Keep alphanumeric-leading rule separate and dot-prefixed: ^([a-z0-9]{6,11})_.+ -> .$1.
• Preserve yt-dlp bracketed ID rule with dot-prefixed replacement.
• Tighten fallback extension cleanup to probable extensions only: (?i).*.[a-z0-9]{1,5}$ -> .
• Update scraper timestamp comment to May 6, 2026.

Risks / assumptions:

• ID lower bound remains 6 for compatibility with existing plugin behavior.
• Numeric and alphanumeric collision handling depends on rule order (numeric rule intentionally first).
• Unknown filename formats that miss all ID rules still fall back to video./x behavior (pre-existing).
• If very short dot-suffix IDs (<=5) exist in the future, fallback may treat them as extensions.

[feederbox826]

only clear likely file extensions (1-5 chars), not "."

then add it to the previous regexes.

If I do, then non-matches will pass the entire input filename to the xvideo api. Are you ok with that?
