feat(sdk-core): support stuck transaction age filters

[bitgo-ai-agent-dev]

What

• Add a sdk-core wallet wrapper for the potentialStuckTxs endpoint.
• Forward optional minUnconfirmedMinutes and minUnconfirmedBlocks filters,
  along with existing endpoint query options.
• Add interface definitions and tests for absent, individual, and combined filters.

Why

• Callers need to filter transactions by unconfirmed age so newly broadcast
  transactions are not surfaced as needing acceleration, while preserving the
  endpoint's existing opt-in and backward-compatible behavior.

Test plan

• Added focused unit tests for query forwarding.
• Run the focused unit test (blocked by dependency installation failure).

Rather than Promise<any>, consider giving this a real return type. The response is an array where each entry is either an ETH-style stuck tx (cause, message, optional nonce/txId/txHex/gasAccelerationFee/etc.) or a UTXO-style one (txId required, optional rbf). Something like:

export interface GetPotentialStuckTxsResult {
  txId?: string;
  cause?: string;
  message?: string;
  nonce?: number;
  txHex?: string;
  txType?: string;
  sendTransfer?: Record<string, unknown>;
  gasAccelerationFee?: { gasPrice?: string; maxFeePerGas?: string; maxPriorityFeePerGas?: string };
  userActionDisabled?: boolean;
  rbf?: boolean;
  coin?: string;
  wallet?: string;
  isFeeAddress?: boolean;
}

getPotentialStuckTxs(params?: GetPotentialStuckTxsOptions): Promise<GetPotentialStuckTxsResult[]>;

Would tighten this up for consumers without needing to model the full union precisely.
