feat(dapi): allow setting max grpc response size

[lklimek]

Issue being fixed or feature implemented

GetRecentCompactedAddressBalanceChangesResponse can have 100 values * 2048 addresses * ~44 bytes each = ~9MB.
Right now, we have a default limit of gRPC response in rs-sdk and rs-dapi set to default 4MB.

This causes errors like:

 error=Grpc(Status { code: OutOfRange, message: "Error, decoded message length too large: found 9037453 bytes, the limit is: 4194304 bytes"

What was done?

Added mechanism to rs-dapi-client that allows setting max response size.
Set max response size for GetRecentCompactedAddressBalanceChangesResponse to 16MB to be safe.

How Has This Been Tested?

To be tested during testnet testing.

Summary by CodeRabbit

• New Features
  • Added configurable maximum gRPC message decoding size to request settings.
  • Optimized message size limits for specific operations: balance change queries now default to 16 MB, while state transition and transaction subscription requests allow explicit override.
  • Enhanced handling of large response payloads across SDKs.

📝 Walkthrough

Walkthrough

A new optional max_decoding_message_size configuration field is added to RequestSettings structs across multiple packages (rs-dapi-client, rs-sdk, wasm-sdk) to allow controlling gRPC maximum decoding message size. The field is propagated through request merging and finalization logic, applied during channel creation, and set with custom overrides for specific request types.

Changes

Cohort / File(s)	Summary
RequestSettings struct extension packages/rs-dapi-client/src/request_settings.rs	Added max_decoding_message_size: Option<usize> field to RequestSettings and AppliedRequestSettings. Updated default() constructor, override_by() merge logic, and finalize() method to propagate the new field.
gRPC channel creation and request overrides packages/rs-dapi-client/src/transport/grpc.rs	Modified PlatformGrpcClient and CoreGrpcClient to apply max_decoding_message_size when creating channels. Updated SETTINGS_OVERRIDES for GetRecentCompactedAddressBalanceChangesRequest (16 MB), WaitForStateTransitionResultRequest (None), and TransactionsWithProofsRequest (None).
SDK defaults packages/rs-sdk/src/sdk.rs	Initialized max_decoding_message_size to None in DEFAULT_REQUEST_SETTINGS.
WebAssembly SDK settings conversion packages/wasm-sdk/src/settings.rs	Extended From<RequestSettingsInput> implementation to initialize max_decoding_message_size to None when converting to RequestSettings.

Poem

🐰 A field hops in, so neat and right,
Decoding sizes, configured tight,
From SDK to gRPC with care we send,
Sixteen megabytes, a generous friend!
Our channels flow with measured pace,
Configuration's gentle embrace. 🎯

65-73: Expose maxDecodingMessageSize in WASM bindings.
Right now this field is always None because the TS interface and RequestSettingsInput don’t accept it, so JS callers can’t configure the limit.
