UX tweaks: bluetooth tooltip, wifi hover details + 6GHz, and skip icon desaturation

[Ziad-Khattab]

Hey!

I wanted to submit a few minor visual and UX tweaks I've been running on my local setup.

Here's what this includes:

• Added a hover tooltip to the Bluetooth icon showing the connected device's name and battery level (pulling from BluetoothStatus).
• Moved the Wi-Fi hover details to show only when hovering directly on the Wi-Fi icon instead of triggering on the whole quick settings container. Also hooked it to refresh network details on hover, which fixes the bug where SSID details would randomly stop showing or go blank.
• Added calculations to support frequencies >5900 MHz so that 6 GHz bands (Wi-Fi 6E/7) show up correctly in the UI.
• Skips desaturating application icons in the dock/taskbar if they aren't part of the active monochrome icon theme (so colored brand icons like Firefox, Steam, etc. don't turn into gray blobs).

Let me know if this looks good to merge!

Thanks @Ziad-Khattab — the actual features here are all useful: the 6 GHz band calc, the Bluetooth device tooltip, the Wi-Fi hover-refresh fix, and skipping desaturation for non-monochrome icons.

The blocker is scope: the diff is 31 files because a "Save local modifications before update" commit pulled in your whole local divergence (a full SoftwareView.qml rewrite, Brightness.qml, TrayService.qml, compositor KDL/dots, etc.) that's unrelated to the described changes.

Could you split this into focused PRs off a clean main — ideally one per feature? The 6 GHz calc and the icon-desaturation skip especially look like easy isolated wins I'd merge quickly.
