Bluetooth panel to support multi adapter

[balloob]

Breaking change

Proposed change

With the Bluetooth adapter being linked from the main menu, it should show information about all available bluetooth adapters at the same time. This PR makes the required updates for that by:

• first card shows all adapters and their warnings
• allocations are now shown alongside the adapter entry
• Move all features into tabs

Type of change

• Dependency upgrade
• Bugfix (non-breaking change which fixes an issue)
• New feature (thank you!)
• Breaking change (fix/feature causing existing functionality to break)
• Code quality improvements to existing code or addition of tests

• The hardcoded string "Bluetooth" should use the localization system instead. Replace with this.hass.localize("ui.panel.config.bluetooth.title") to maintain consistency with the rest of the codebase and support internationalization.

I'm pushing back on features that are putted into the beta milestone. Don't take it as we don't want to have it, or we don't have interest in this cool feature you're working on during the holidays, it's just that we should respect that there's no priority queue.

[balloob]

Okay. Then lets remove the Bluetooth menu item for now as it was broken, and this PR fixes it.

LGTM. Should we merge it without the milestone?

[piitaya]

I guess this should fix that issue so may be we can consider milestone? I will take a look

We lost making it obvious that an adapter (likely Shelly) doesn't support making active connections which is a key confusion point for users. Without this, users might wonder why their Bluetooth devices aren't working with certain proxies

[bdraco]

I think we need to keep "ui.panel.config.bluetooth.no_active_connection_support" but a shorter version for the secondary text

[bdraco]

I re-added the milestone since this solves the above issue with the Bluetooth menu item. Maybe we drop the last commit because of the feature creep but it feels like nitpick territory so I'm fine with it either way.

@bdraco I removed the last commit and added "no connection slots" when needed.
