[Bug]: Minify Revit UI state desync after cross-model view switch (reproduced on 5.3.1; same code path in 6.1.0 and latest develop)

[OriAshkenazi]

✅ Pre-Flight checks

• I don't have SentinelOne antivirus installed (see above for the solution)
• I have searched in the issues (open and closed) but couldn't find a fully equivalent issue
• I have searched in the pyRevit Forum for similar issues
• I already followed the installation troubleshooting guide thoroughly
• I am using the latest pyRevit Version

🐞 Describe the bug

Minify Revit UI can desynchronize from actual ribbon visibility when switching between views in different open models.

Observed behavior:

• Minify button remains active (orange / on)
• MINIFYUIACTIVE remains True
• some configured hidden tabs reappear after cross-model view activation

Reproduced tabs that reappear:

• Steel
• Precast
• Massing & Site

Configured hidden tabs that remained hidden in this repro:

• Content Catalog
• In-Place Model
• In-Place Mass

⌨ Error/Debug Message

No exception dialog appears. This is a state/visibility mismatch.

🎞️ To Reproduce

1. Open Revit 2023.
2. Open two project models simultaneously.
3. Configure Minify hidden tabs:
   • Steel, Precast, Massing & Site, Content Catalog, In-Place Model, In-Place Mass
4. Enable Minify Revit UI.
5. Verify tabs are hidden.
6. Activate a view in the second model.
7. Return to a view in the first model.
8. Observe Steel/Precast/Massing & Site are shown again while Minify stays active.

🏲️ Expected behavior

• With Minify Revit UI active, all configured hidden tabs remain hidden across cross-model/view activations until Minify is explicitly disabled.
• Minify button icon/state remains synchronized with actual applied ribbon visibility after context switches.

Proposed fix heuristic for maintainer review (pre-implementation):

1. Use MINIFYUIACTIVE plus configured hidden_tabs as the single source of truth.
2. Re-apply update_ui(config) when Revit context changes (at least ViewActivated; add document-activation/idling fallback only if needed).
3. Guard against duplicate event subscriptions in smartbutton lifecycle.
4. In __selfinit__, initialize icon and applied visibility from current env/config so startup/reload states are consistent.
5. Keep current behavior unchanged when Minify is off.

Maintainer approval requested: please confirm this heuristic before implementation. No implementation work should start until approval is given.

Additional context

• Runtime reproduction above was performed on pyRevit 5.3.1 attached to Revit 2023.
• Re-check against latest source:
• Pulled origin/develop to commit 6f1ea3fa.
• Fetched v6.1.0.26047+2255.
• Verified Minify bug-path files are byte-identical across:
• v6.0.0.26032+2145
• v6.1.0.26047+2255
• origin/develop (and local develop after pull)
• Relevant unchanged files:
  • extensions/pyRevitTools.extension/pyRevit.tab/Toggles.panel/toggles1.stack/MinifyUI.smartbutton/minifyui.py
  • extensions/pyRevitTools.extension/pyRevit.tab/Toggles.panel/toggles1.stack/MinifyUI.smartbutton/script.py
  • extensions/pyRevitTools.extension/pyRevit.tab/Toggles.panel/toggles1.stack/MinifyUI.smartbutton/config.py
• Current Minify logic still applies tab visibility only in update_ui() and only when toggle/config runs, with no activation event hook in Minify __selfinit__.
• Possible overlap with #1716.
