feat(commands): localize punctuation voice commands (#640)

[jatinkrmalik]

Description

Voice command phrases (comma, period, new line, …) were hardcoded English-only. With recognition language set to Italian/French/etc. and voice commands enabled, spoken punctuation in that language was injected as literal words (#640).

This wires recognition language into CommandProcessor and merges localized punctuation / line-break aliases (IT, FR, DE, ES, PT, NL, PL, RU), while always keeping English phrases. Also adds English dot → ..

Fixes #640

Type of Change

• ✨ New feature (non-breaking change which adds functionality)
• 📖 Documentation update
• ✅ Test update

Changes

• New command_phrases.py with locale alias maps keyed by Whisper ISO codes
• CommandProcessor(language=…) / set_language() rebuilds aliases
• SpeechRecognitionManager passes language on init and reconfigure
• Punctuation attach-left spacing keyed by replacement char (works for all locales)
• Docs / settings tooltip / PRODUCT.md updated
• Tests for IT/FR/DE/ES/PT, English dot, auto (English-only aliases), and set_language

Out of scope

• Localized action/format phrases (delete that, undo, capitalize, …) remain English
• User-custom command phrases (already on roadmap)
