Offline dictionary (#45)
* Added support for external dictionary apps and a dictionary settings sheet. * Refactored external dictionary integration and improved package visibility - Updated `AndroidManifest.xml` with `<queries>` for common dictionary apps and intent actions (`PROCESS_TEXT`, `SEARCH`, `SEND`) to support Android 11+ package visibility. - Refactored `ExternalDictionaryHelper` to streamline dictionary discovery using `Intent.ACTION_PROCESS_TEXT` and `colordict.intent.action.SEARCH`. - Added a package blocklist in `ExternalDictionaryHelper` to filter out system services (e.g., Samsung Pass, GMS) from dictionary lists. - Simplified `launchDictionary` logic to prioritize `PROCESS_TEXT` intents. - Fixed a bug in `PdfViewerScreen` to only show the dictionary upsell dialog when `useOnlineDictionary` is enabled. * Refactored dictionary settings into a dialog and updated dictionary selection logic. - Renamed `DictionarySettingsSheet` to `DictionarySettingsDialog` and converted it from a bottom sheet to a formal dialog. - Redesigned the dictionary settings UI with a clearer distinction between AI and external app modes. - Added a "Search" option to the external dictionary list that triggers a web search. - Updated `ExternalDictionaryHelper` to include a package blocklist and support for generic web search intents. - Simplified `PdfHelper` by removing Pro user checks for the "Dictionary" action. - Updated icons for dictionary settings across the EPUB and PDF readers.
