Address review: exempt LND subscription streams from the request timeout

Browse source 
The 10-minute timeout added for review feedback would have aborted
LND's long-poll subscription streams (/v2/invoices/subscribe and
/v2/router/track), which legitimately stay open until an invoice
settles or a payment resolves - breaking real-time notifications for
any invoice paid more than 10 minutes after creation.

The wrapper now honors a per-call options.timeout (0 disables the
bound, axios semantics; the 10-minute default still applies everywhere
else), and both subscription calls pass timeout: 0. They also copy the
options object instead of mutating it: addInvoice hands the
session-cached options to subscribeToInvoice, so setting the timeout
in place would have leaked an unbounded timeout to every subsequent
request for that node (getOptions resets form/body/qs but not
timeout).

Verified on the regtest fixture: with a websocket client connected as
alice's frontend, creating an invoice opens the subscription stream,
it survives idle, and paying it from the CLN node delivers the SETTLED
event over the websocket in real time. The per-call override was also
verified directly (timeout: 1000 aborts a slow upstream with
ECONNABORTED; timeout: 0 waits it out). Both API suites (31 read + 12
write checks) re-pass.
