fix(l10n): fix strings extraction

- handle `SOURCES` recursively, rather than spelling all the paths out;
most of them were outdated and some still missing
- let the Python script skip existing translations (in case we need to
manually add plurals)
- updated qml_en.ts as a result of these changes

Stats:
```
Updating '../../ui/i18n/qml_en.ts'...
    Found 1703 source text(s) (109 new and 1594 already existing)
    Kept 35 obsolete entries
    Same-text heuristic provided 35 translation(s)
