use the new `quick_bridge` adapter and do few changes to make TUI work with new backend.
TUI will probably be rewritten at some point, this is just an update to keep it working.
`urwid` has been updated to have a version working with Python 3.14.
- D-Bus bridge check if it can import GLib, to raise early a BridgeInitError if it's not
possible
- PB bridge now do lazy import of `reactor` to avoid race condition in Twisted loop
initialisation.
- regenerated bridges.
This is a huge configuration refactoring.
The configuration system now uses Pydantic settings, with better validation, better
support for environment variables and other goodies.
The main config files now use TOML instead of INI, this allow for better handling of
complex types, notably dict.
Plugins, components and frontends can declare their config settings in a class which will
be imported dynamically.
