Add Command Palette component with global shortcut and route integration

[srozen]

• Implemented CommandPaletteComponent with keyboard navigation, route filtering, and localization support.
• Integrated global Cmd/Ctrl + K shortcut for activation.
• Updated LayoutContainer to include the Command Palette.
• Extracted reusable route entry utilities and updated existing navigation logic for consistency.
• Added tests for route entry extraction, palette functionality, and shortcut behavior.

Improvements needed:

• The current display is a bit weird as it simply takes available information form the route being the name, the icon and the path. There should be a prettier way to define the information reported in the command palette, maybe something specifically dedicated to that (with fallback), e.g. a description and a title ?
• Adapt the search to work with those fields
• Remove the icon display as this does not serve a good UX with routes having icons and others not
• Add keyboard navigation hints at the footer of the command palette
• Align the style with WeFa standards (make it a bit more pretty and clean)

Read command entries from router matcher

This computes palette entries from router.options.routes, which only reflects the initial router config and does not include routes registered later with router.addRoute(...) (for example, plugin-driven routes such as those added in legalConsentPlugin.install). As a result, dynamically injected routes can never appear in the command palette even if they set meta.wefa.showInCommandPalette, so users lose navigation paths that exist in the app. Build entries from the live matcher (router.getRoutes()) instead of the static options array.
