* test: Add tests for uncategorized filter across all locales
Adds two tests to catch the bug where filtering for "Uncategorized"
transactions fails when the user's locale is not English:
1. Tests that filtering with the locale-specific uncategorized name
works correctly in all SUPPORTED_LOCALES
2. Tests that filtering with the English "Uncategorized" parameter
works regardless of the current locale (catches the French bug)

* fix: Fix uncategorized filter for French, Catalan, and Dutch locales
The uncategorized filter was failing when the URL parameter contained
"Uncategorized" (English) but the user's locale was different. This
affected 3 locales with non-English translations:
- French: "Non catégorisé"
- Catalan: "Sense categoria"
- Dutch: "Ongecategoriseerd"
The fix adds Category.all_uncategorized_names which returns all possible
uncategorized name translations across supported locales, and updates
the search filter to check against all variants instead of just the
current locale's translation.
