feat(ramps): add option to make requests without updating controller state

[georgeweiler]

Explanation

This PR adds a doNotUpdateState option to ExecuteRequestOptions that enables external consumers to use RampsController methods without modifying the controller's state.

• Added doNotUpdateState?: boolean to ExecuteRequestOptions in RequestCache.ts
• Added CacheOptions type for stateful methods (init, setUserRegion, hydrateState) that should not accept doNotUpdateState
• Updated getCountries(), getTokens(), getProviders(), and getPaymentMethods() to conditionally skip state updates when doNotUpdateState: true
• The option is passed through method signatures including all trigger methods
• Request caching and deduplication still work normally - only the domain state updates are skipped

Use Case

External teams consuming the RampsController may need to call API methods (e.g., getTokens, getProviders) to fetch data for display or comparison purposes without polluting the controller's persisted state. For example:

// Fetch tokens for a different region without affecting the user's current state
const otherRegionTokens = await rampsController.getTokens('fr', 'buy', {
  doNotUpdateState: true,
});

Note

Introduces an opt-in way to call RampsController fetchers without touching controller state, useful for ad‑hoc comparisons or alternate views.

• Adds doNotUpdateState to ExecuteRequestOptions and new CacheOptions type; updates signatures for init(), setUserRegion(), hydrateState(), and trigger methods accordingly
• Updates getCountries(), getTokens(), getProviders(), and getPaymentMethods() to skip state writes when doNotUpdateState: true while still updating the request cache (dedup remains intact)
• Exports CacheOptions; adjusts tests to cover non-mutating behavior and cache updates; minor import additions (createCacheKey)
• Updates changelog with the new option
