revert: restore full config overwrite + Common Config Snippet (revert 992dda5c)

Revert the partial key-field merging refactoring introduced in 992dda5c, along with two dependent commits (24fa8a18, 87604b18) that referenced the now-removed ClaudeQuickToggles component. The whitelist-based partial merge approach had critical issues: - Non-whitelisted custom fields were lost during provider switching - Backfill permanently stripped non-key fields from the database - Whitelist required constant maintenance to track upstream changes This restores the proven "full config overwrite + Common Config Snippet" architecture where each provider stores its complete configuration and shared settings are managed via a separate snippet mechanism. Reverted commits: - 24fa8a18: context-aware JSON editor hint + hide quick toggles - 87604b18: hide ClaudeQuickToggles when creating - 992dda5c: partial key-field merging refactoring Restored: - Full config snapshot write (write_live_snapshot) for Claude/Codex/Gemini - Full config backfill (settings_config = live_config) - Common Config Snippet UI and backend commands - 6 frontend components/hooks for common config editing - configApi barrel export and DB snippet methods Removed: - ClaudeQuickToggles component - write_live_partial / backfill_key_fields / patch_claude_live - All KEY_FIELDS constants
