refactor: migrate Phase 2 FutureProvider functions (5-15/15) ✅

Migrated 11 more providers to @riverpod functions:
Core providers:
- userSettingsProvider → userSettings
- conversationSuggestionsProvider → conversationSuggestions
- userPermissionsProvider → userPermissions
- foldersProvider → folders
- userFilesProvider → userFiles
- knowledgeBasesProvider → knowledgeBases
- availableVoicesProvider → availableVoices
- imageModelsProvider → imageModels

Feature providers:
- promptsListProvider → promptsList
- toolsListProvider → toolsList

Bonus notifiers also migrated:
- activePromptCommandProvider → ActivePromptCommand
- selectedToolIdsProvider → SelectedToolIds

Phase 2 Complete! All 15 FutureProvider functions migrated.
All provider names unchanged, no breaking changes.
Analyzer passing, only pre-existing keepAlive warnings.
