🎨 Palette: WebUI/UX Enhancement

Implemented immediate visual feedback for multiple asynchronous WebUI interactions by hooking them into the native notify('...', 'working') mechanism.

Changes

• Editor Save: Appended a notify('Saving...', 'working') to the handleSave() function so users immediately know their file save has initiated.
• Language Reloading: Modified the inline loadLanguage() call on the Guide tab to explicitly post a notify('Loading...', 'working') and chain the promise resolution to notify upon completion.
• Toggle Settings: Added a notify('Updating...', 'working') to the start of the toggle(setting) function, eliminating the silent delay when interacting with toggles.
• Log Refreshing: Hooked fetchLogs() to post a 'working' notification to reassure the user while waiting for log retrieval.

Why this is needed

Previously, several background or network-dependent tasks on the WebUI dashboard omitted visual cues. Users could tap "Refresh Logs" or "Reload Language File" and not realize the process had started, leading to poor feedback and a broken mobile experience. This patch unifies loading states.
