Description

Fixes invalid dev-panel-ramps-order traffic hitting the provider's Get Orders by ID endpoint (500s on LIVE).

The Navigation Dev Panel (internal-only, gated by MM_ENABLE_SETTINGS_PAGE_DEV_OPTIONS) seeded a mock Ramps order into persisted RampsController state via addOrder():

providerOrderId: dev-panel-ramps-order
provider.id: paypal
That order persisted across launches. On internal/experimental builds that use the production ramps environment, it reached the provider's live endpoint with an invalid order ID. This started after the ramps seed landed in #31037 (~June 4).

Changes:

• Remove the Navigation Dev Panel entirely (component, mock params, Developer Options entry, route, and references) so nothing can seed these orders again.
• Add migration 140 to purge dev-panel sentinel artifacts from affected devices on next launch:
• RampsController.orders → dev-panel-ramps-order (the incident)
  fiatOrders.orders → dev-panel-aggregator-order, dev-panel-deposit-order, dev-panel-sell-order
• BridgeStatusController.txHistory / TransactionController.transactions → dev-panel-bridge-tx
  Production users were never affected (dev panel not reachable in prod builds). Migration 140 is a no-op for them and only for RC users.

Fixes: Test seeding ramp with order ID dev-panel-ramps-order bug for non-production users

Manual testing steps

 Background:
    Given the app is built with MM_ENABLE_SETTINGS_PAGE_DEV_OPTIONS enabled
    And the user has previously opened the Navigation Dev Panel
    And the user navigated to the Ramps Order Details entry in the panel
  
Scenario: Navigation Dev Panel is no longer available
    Given the user opens Settings
    And the user opens Developer Options
    Then the "Open Navigation Dev Panel" button is not shown
    And the NavigationDevPanel route is not registered in the navigator
  
Scenario: Dev panel no longer seeds a mock Ramps order
    Given the user is on Developer Options
    When the user attempts to open the Navigation Dev Panel
    Then the Navigation Dev Panel cannot be opened
    And no new order with providerOrderId "dev-panel-ramps-order" is added to RampsController state
