Add accessible state to the On/Off controls.

Button only forwards props and adds no state semantics. Add aria-pressed or radio semantics to each option, and associate each group with an accessible label.

expose their selected state through aria-pressed or equivalent radio semantics,
and associate each two-option group with its corresponding label. Preserve the
existing click handlers and visual selected-state variants.

Report and recover from persistence failures.

The setters update local state before persistence. If updateSettings() fails, the UI shows a setting that was not saved and only writes an error to the console.

Show a user-facing error and restore the last persisted values, or return the failure to the caller for display. As per coding guidelines, “Implement error handling with user-friendly messages.”

Make writing-assistance persistence atomic.

Each setter reads a complete Settings snapshot and then writes a modified copy. If setSpellCheckEnabled and setAutoCorrectEnabled overlap, the last write can restore stale values and lose the other update.

Add one Tauri command that updates both writing-assistance fields atomically. Use that command from both setters. This also prevents these setters from overwriting unrelated settings that changed after getSettings() resolved.

without reading and rewriting a full Settings snapshot. Update
setSpellCheckEnabled and setAutoCorrectEnabled to call this command with the
intended spell-check and auto-correct values, while preserving their local state
updates and dependency behavior; ensure unrelated settings are not overwritten
during concurrent updates.
