Privacy-preserving app tracking

[hsjoberg]

We should consider adding some kind privacy-preserving app tracking.
It should be opt-in and clearly stated to only be used to know where common pitfalls are etc.

• Initial support for sentry.
• Make UI changes on how to add tracking.
• Come up with list of items that have to be tracked.
• Come up with a scalable way to actually throw sentry exceptions.

Here is an example where we capture an exception with sentry.

export const sendLnaddr = async (
  addr: string,
  amountSat: number,
  comment: string,
): Promise<LnurlPaymentResult> => {
  try {
    const result = await sendLnaddrNitro(addr, amountSat, comment);
    return result;
  } catch (error) {
    console.error("Failed to send to lightning address:", error);
    Sentry.captureException(
      new Error(
        `Failed to send to lightning address: ${error instanceof Error ? error.message : String(error)}`,
      ),
    );
    throw new Error(
      `Failed to send to lightning address: ${
        error instanceof Error ? error.message : String(error)
      }`,
    );
  }
};
