[UI - Wallet Stability] Rename `NetworkSelector` component to `RouterPanel` and analyse if some improvements needed

Design

Design 2

• Rename NetworkSelector component to RouterPanel (or more appropriate name).
• Quick analysis if there are some dependences or easy api cleanups we can do now.
• Maybe create some subtasks for next improvements setps.

Notes:

• There will be a new design of the Transactions Card in the next milestones so probably it does'n make sense to put a lot of effort now
• There will be the new router V2 that probably will need some additional information to be displayed but also effort for the next milestone.

There's an improvement to add for this milestone for the fees panel inside the RouterPanel component. Here the task: https://github.com/status-im/status-desktop/issues/14208

Created draft PR with the major part of the refactor but since there's no capacity to work on the qml tests for each small component neither adding them to storybook, it doesn't add a lot of value to the release 2.30, without the small components testing.

It's moved to next milestone. During stability phase we will work on components testing and then integrating the already done work into the app.

@micieslak there's a draft pr created and missing things are:

• Add the following components to Storybook and create qml tests for each one:
  • NetworkCardsComponent
  • NetworksSimpleRoutingView
  • NetworksAdvancedCustomRoutingView
  • FeesView

The SendModal will go through a re-design
