More ngrams

Part of #851

[Copilot]

Pull request overview

This PR adds explicit ngramFile configuration to language definitions (rather than deriving the filename from dictionaryFile), enabling next-word prediction support per language as part of issue #851. It also tweaks soft-key behavior (new edit-text icon/command for RF3, fixing SoftKeyNumberSwipeable to use a new COLLECTION_SWIPE command collection) and changes the MindReader seeding flow to handle languages without spaces between words via a new setTokens() method. The UsageStatsScreen truncation now also resets the per-language ngrams revision so factory n-grams are re-imported.

Changes:

• Replace derived ngram file paths with an explicit ngramFile: property on every language YAML; wire it through gradle parsing and validation.
• Add MindReaderContext.setTokens() for pre-tokenized seeding (non-space languages) and refactor MindReader.seed() accordingly; drop the unused return value from setContext().
• Introduce COLLECTION_SWIPE command set (including cut/copy/paste), new ic_fn_edit_text icon, and use the edit-text command's icon in SoftKeyRF3.
