saubyk a8baba12bb Replace deprecated request/request-promise with axios
request has been deprecated since 2020 with an unfixed SSRF advisory and
pins vulnerable copies of form-data (critical), qs, tough-cookie and
uuid - 8 of the 13 remaining production audit findings, none fixable by
version bumps (issue #1634, item 1).

All 36 backend files that imported request-promise now use a small
compatibility wrapper (server/utils/request.ts) backed by axios, which
is already a production dependency. The wrapper accepts the existing
options shape (qs, form - object or pre-encoded string, body,
baseUrl/uri, rejectUnauthorized, json), resolves with the response body
directly, and rejects with a plain object mirroring request-promise's
StatusCodeError/RequestError shape, so CommonService.handleError works
unchanged (ECONNREFUSED -> 503, Eclair StatusCodeError -> 500, nested
error body extraction). Auth headers are excluded from rejected errors
so they cannot leak into logs. Callers without json: true (block
explorer, currency rates) still get raw text bodies, and LND's
line-delimited /v2/router/send stream still surfaces as a string for
the existing parser.

Only behavioral code change: CLN verifyMessage used request-promise's
callback style and was ported to the same promise style as signMessage;
four Eclair handlers gained explicit returns to satisfy
noImplicitReturns once the import became typed.

Production npm audit drops from 13 findings (2 critical) to 6 low, all
in the crypto-browserify/elliptic chain tracked in #1634.

Verified against the docker regtest fixture with 43 API checks across
LND, Core Lightning and Eclair: reads, invoice creation, a routed LND
payment over the streaming endpoint, cross-implementation payments from
CLN and Eclair, message sign/verify, channel backup to disk, and
bad-invoice/node-unreachable error mapping. Lint and both production
builds are clean.
