fix(build): stop disabling the embedded daemon on full-node builds (1.3.0 regression)

The 1.3.0 lite-capability work gated isUsingEmbeddedDaemon() on the compile flag
DRAGONX_ENABLE_EMBEDDED_DAEMON (in 1.2.0 it was hardcoded true, so the daemon
always launched). The lite branch in CMakeLists set that flag OFF with
`CACHE BOOL ... FORCE`, which POISONS the build dir's cache: a later full-node
reconfigure of the same dir keeps the forced-OFF value (the full-node branch
never re-asserts it), so embeddedDaemonAvailable=false and the wallet extracts
dragonxd but never starts it — exactly the reported "unpacks dragonxd.exe but
does not start the daemon, manual start works."

Note the two gates are independent: the binary is EMBEDDED/extracted via build.sh
(HAS_EMBEDDED_DAEMON), while LAUNCHING is gated by DRAGONX_ENABLE_EMBEDDED_DAEMON
— so they diverged (extract yes, launch no).

The forced cache write was also pointless: makeWalletCapabilities() already
forces the embedded-daemon capability off for any lite build via
`fullNodeBuild && embeddedDaemonCompiled`, so lite never launches a daemon
regardless of the flag.

Fix:
- CMakeLists: remove the FORCE cache poisoning (the root cause).
- build.sh: set DRAGONX_ENABLE_EMBEDDED_DAEMON explicitly per variant (ON for
  full-node, OFF for lite), mirroring the existing DRAGONX_BUILD_LITE handling,
  so an already-poisoned build dir is HEALED on the next build rather than
  silently keeping the stale OFF.

Verified: a poisoned Windows cache (=0) flips to =1 on reconfigure; full-node
builds define =1, lite =0; tests + hygiene green.
