feat: add block display text limit settings

Add configurable limits for generated block display text and wire them
through UI, defaults, localization, and usage logic.

- Add blockDisplayWordLimit and blockDisplayCharLimit to settings with
  defaults (3 words, 5 chars).
- Expose new settings in the Settings tab show the two limit inputs
  only when autoBlockDisplayText is enabled and save changes.
- Use the configured limits in main generation logic (fall back to
  defaults if unset) to trim English-like text by words and other
  languages by characters.
- Add i18n keys and translations for labels and descriptions in all
  languages.

This allows users to control how much text is included when the plugin
auto-generates display text for block links.
