Fix: correct regex for file-preview URL re-signing (#25620)
Fixes #25619

The regex patterns for file-preview and image-preview contained an unescaped `?`, 
which caused incorrect matches such as `file-previe` or `image-previw`. 
This led to malformed URLs being incorrectly re-signed.

Changes:
- Escape `?` in both file-preview and image-preview regex patterns.
- Ensure only valid URLs are re-signed.

Added unit tests to cover:
- Valid file-preview and image-preview URLs (correctly re-signed).
- Misspelled file/image preview URLs (no longer incorrectly matched).

Other:
- Fix a deprecated function `datetime.utcnow()`
