fix fast-groups toggle + widget sync in frontend (fast_actions/fast_groups_muter)

[tlennon-ie]

Summary

This PR fixes a frontend bug in the RGTHREE custom nodes where the "Fast Actions" button and the "Fast Groups" widgets would not reliably toggle group enable/bypass state (the button seemed to toggle only once or behave directionally). The issue was caused by a mix of:

• reading widget boolean state from widget.value (an object) instead of the FastGroupsToggleRowWidget boolean accessor widget.toggled,
• and not always letting nodes handle their own action via handleAction, which can lead to stale UI widget state unless a recompute/refresh is run afterwards.

Changes

• Normalize widget boolean reads (use widget.toggled if present, fallback to widget.value) in fast_groups_muter.js.
• Prefer calling node.handleAction(action) from the Fast Actions button if the node implements it. After calling handleAction, force a widget refresh and schedule the fast-groups service recompute to ensure UI state and internal group caches are synchronized.

Files changed

• custom_nodes/rgthree-comfy/web/comfyui/fast_groups_muter.js
• custom_nodes/rgthree-comfy/web/comfyui/fast_actions_button.js

Testing

• Manual: Verified locally that Toggle/Enable/Bypass now flips groups back-and-forth reliably with toggleRestriction = "always one". See gif animation of the button working on latest comfyui version as of today
