feat(widget): add simple and advance modes switching

[effie-ms]

Which Linear task is linked to this PR?

https://linear.app/lifi-linear/issue/EMB-451/enable-simple-and-advanced-jumper-modes-on-widget

Why was it implemented this way?

TBD:

1. Enabling vertical rail/switch for "Simple" and "Advanced" modes with tabs: storing tab "presets" as separate modes (similar to "split" with 2 tabs), or as a new config variable?
2. Storing the vertical switch component on playground or widget side?

Implementation:
The existing SplitModeStore was transformed into more general HeaderTabsStore - to store all available and currently selected tab activeTab. Each tab has label, mode, modeOptions.

jumper-simple and jumper-advanced resolve to 3 tabs (per design), each with a corresponding mode (default, swap, bridge, etc).

NB: widget needs to be wider to store all 3 tabs.

TBA
