Add Degen Mode, swap settings panel

[christianbaroni]

Fixes APP-1677

What changed (plus any additional context for devs)

• Adds a swap settings panel, which contains the following settings:
  • Degen Mode
    • If enabled, the review sheet is skipped, and Flashbots and slippage settings are relocated to the settings sheet
  • Preferred Network
    • Defaults to Auto
    • If a preferred network is set, the default input asset logic is adjusted to prefer the highest-value asset on the specified network, if one exists — otherwise falls back to the overall highest-value asset
• Adds a reusable ChainContextMenu component
• Fixes animated image flickering in the swap coin icons and the dapp browser search results
• Migrates usages of GestureHandlerV1Button to GestureHandlerButton (RNGH v1 → v2)
  • Leaves one instance of GestureHandlerV1Button in SwapSlider because it relies on the ref prop
• Fixes issues causing slippage not to update when the input asset network changes
  • Previously, the default slippage value was set only once when the swap UI was initially mounted — it wasn't being updated when the input asset network was changed. Now, if the user hasn't overridden the default value, slippage will update to the correct default when the input asset network changes.
• Fixes the 3_homeScreen e2e test and increases the max number of parallel workers, which speeds up tests a bit
