Merge tls into master: bring in subscription ownership, keep all TLS/stability work

tls and master diverged from a July 2024 fork point and never
reconciled - tls carries ~19 months of real socket/TLS stability
fixes (uninitialized tlsInfo, TCPServer::connectionRequest()
unconditionally initializing TLS, the WANT_READ write busy-spin, the
console authentication fix from this session), while master
independently picked up a Subscription/SubscriptionManager rework
(MString-based ownership tracking: owner/ownership/selection/time
fields and a working subscriptionOwner() method) that tls never had.

Every file both branches touched was resolved by keeping tls's side
entirely (Command.h, Socket.cpp, TCPServer.h, TCPSession.cpp/h,
TCPSocket.h were pure reformatting on master's side, or an
alternate/superseded fix for a bug tls already fixed a different way -
e.g. master's TCPSession uuid/alias handling vs tls's existing
uuid_unparse-based fix), with two deliberate exceptions:

- TCPServer.cpp's constructor was missing the
  commands.add(subscriptions, "publish"/"subscribe"/"catalog"/...)
  wiring master had - without it, SubscriptionManager existed but was
  completely unreachable through the normal command dispatch. Restored
  on top of tls's TLS-aware constructor.

- SubscriptionManager.cpp's "invite" command handler had a real
  incompatibility: master's version assigned into an `invitee` member
  typed as coreutils::MString via a stray `(coreutils::MString *)`
  cast that doesn't match the member's actual (non-pointer) type, and
  called session.server.getSessionByAlias() against a TCPServer
  reference - tls made TCPSession::server a pointer (part of removing
  the separate TCPSession2 class), so that call site no longer
  compiles as written. Took tls's cleaner local-variable version
  instead (functionally identical - looks up a session by alias and
  forwards an invite message) and removed the now-unused `invitee`
  member from SubscriptionManager.h.

One additional compile fix needed after resolving conflicts:
Subscription::subscriptionOwners is an MString (master's ownership
design), but TCPSession::alias is void* (tls's identity mechanism,
unchanged and depended on elsewhere) - MString has an implicit
constructor from void* already used successfully elsewhere in this
same file (the "publish" handler's Subscription constructor call),
but operator== doesn't accept the same implicit conversion, so
removeSessionSubscriptions()'s ownership check needed an explicit
coreutils::MString(session.alias) construction to compile.

Also drops output/main (a stray checked-in compiled binary, already
removed on tls) and the doxygen docs/html output (already removed on
tls, was carried on master since the fork).

Verified: full ServerCore rebuild (./compile) succeeds with zero
errors or warnings beyond the one compile fix documented above.
