test(e2e): remove Tenderly hosts from E2E allowlist (MMQA-1787)

Removes all four Tenderly entries from ALLOWLISTED_HOSTS by replacing
the live network dependency with a default RPC mock and confirming
the existing fixtures don't actually need Tenderly fork state.

- api.tenderly.co + rpc.tenderly.co: zero references in tests/app code,
  delete as vestigial
- virtual.linea.rpc.tenderly.co: already mocked by cardholder-mocks.ts
  for the only specs that exercise it (card-home-add-funds, card-button)
- virtual.mainnet.rpc.tenderly.co: add a regex default mock returning
  eth_chainId 0x1 and standard JSON-RPC stubs (Tenderly Mainnet is
  semantically chain 1, so 0x1 is correct). Used by the on-ramp specs,
  which assert UI state, not chain state.

Also removes the Detox blacklist entry for rpc.tenderly.co and deletes
tests/helpers/tenderly/tenderly.js — the helper's only function
(Tenderly.addFunds) was never called, making tenderly_setBalance dead
code.

ALLOWLISTED_HOSTS is now down to 7 entries.
