fix: support wildcards/glob patterns in reload_extra_files

[digital-wizard48]

Summary

• The reload_extra_files configuration option did not support wildcard/glob patterns, requiring users to explicitly list every file they wanted to watch.
• This fix expands glob patterns in reload_extra_files using glob.glob() with recursive=True support before passing the file list to the reloader engine.
• If a pattern doesn't match any files, it is passed through as-is (preserving existing behavior for explicit file paths).

Example

Users can now use:

reload_extra_files = ['ui/*/config.json', '**/*.yaml', '*.js']

instead of listing every file explicitly.
