Adds a background body-prefetch mechanism with network-awareness and a user-configurable cache size limit to keep email bodies available offline without downloading the entire mailbox. - Schema v38: adds `prefetch_mode` and `body_cache_limit_mb` columns to `user_preferences` (defaults: wifiOnly / 100 MB). - `PrefetchMode` enum (disabled / wifiOnly / always) in the model. - `BodyCacheService`: fetches bodies for uncached emails (newest first, batch of 20), evicts oldest cached bodies when the size limit is exceeded. - Registers a separate WorkManager periodic task (`si_bg_prefetch`) with `NetworkType.unmetered` (Wi-Fi only) or `NetworkType.connected` (any) based on the stored preference; cancels the task when disabled. - On app startup, reads the stored preference and re-registers the task with the correct constraint. - Preferences screen: radio group for prefetch mode + dropdown for cache size limit (50 / 100 / 200 / 500 MB).
