fix(lib): thread from_host through the wire format and the job-submit interning object (bug-1676, gitea #44)

Browse source 
- src/schema/controller.capnp: JobSubmitData gains
  fromHost @10: Text $C.mapname("from_host") -- auto-regenerates
  controller.capnp.c/h via the existing meson capnpc-c custom_target.
- src/include/xce/types.h: job_submit_data_t gains char* from_host.
- src/lib/jobj.c: jobsub_init/jobsub_destroy (the hand-written,
  ref-counted, content-deduped job-submit interning object -- not
  auto-generated) thread from_host through the deep-copy, the dedup
  identity comparison, and the destroy path.

Closes the wire-format half of the round-trip: from_host now survives
from the apiserver's submission all the way through the controller and
back on every subsequent job-state push, and rides along for free in
the existing WAL_JOB_SUBMIT persistence across a controller restart.
Did not need to touch job.c's build_job_submit_payloads() (bare
pointer borrow of the already-decoded submit struct) or any WAL
apply-path code (capnp_encode_job/decode_Job already generically
handle the whole xce_job_t including its full .submit sub-struct).
