Merge upstream v1.2.19 into the fork

Merges upstream tag v1.2.19 (9e39a50) into merge/upstream-1.2.18 (991853f).
Unlike the 1.2.15->1.2.18 replay, bc3de30 is a true ancestor of our branch via
a9b4f89, so this is an ordinary three-way merge with merge-base bc3de30.

Delta: 36 files, +3265/-163, the Tor onion transport (managed Tor, signed
direct onion endpoints, onion-only dial mode) and the nHDNext restore fix.
src/main.cpp, main.h, script.cpp/h and db.cpp/h are byte-identical between the
two tags, and the poll() socket loop carries no diff hunks, so the merge is
consensus-neutral and the soak-tested socket paths are unchanged. relay/ is
untouched; the payout ledger (rpc.cpp) is untouched.

7 conflict blocks in 6 files, resolved as follows.

Makefile -- VERSION. Ours: stays 1.2.19+sec with the naming comment updated,
so artifacts from this tree cannot be mistaken for the upstream release.

src/Makefile, src/makefile.mingw -- HEADERS list. Ours (no market.h) plus
their tor.h. NODE_OBJS auto-merged correctly: no market.o, tor.o present.

src/selftest.cpp -- known-tests list. Union: payout-ledger (ours) and
managed-tor (theirs).

src/main_gui.cpp -- one block. Our /dumpaddresses kept; their
BtfStopManagedTor() on the StartNode failure path taken. The /rvrelay pin,
/noannounce and the marketplace removal auto-merged and were verified intact.

src/nostr.cpp -- two blocks in ResolveDescriptor. Signature takes both
out-params (our fExchangeOk, their rawOut). The body keeps our
drain-to-EOSE read -- returning early poisons the pooled socket for the next
caller -- and adds their rawOut capture. Our TLS 1.2 floor
(SSL_CTX_set_min_proto_version) is untouched by this merge; upstream 1.2.19
still has no floor of its own.

Upstream's release commit also added four build logs and a compiled Python
cache (build-1219.log, build-17.log, build-appimage.log, build-node.log,
scripts/__pycache__/bitflash_chain.cpython-313.pyc). Removed here; they are
build output, not source.
