docs: fix round 1 (F9) -- Holy Name of Jesus is missing a real office, not just a name

A second, more severe gap than the identity-shaped one already
recorded: RG 17(a)'s own 2-5 January window, unlike Holy Family's
7-13 January (never empty, register section 6.2), CAN be empty of a
Sunday -- the calendarium carries an explicit fallback for it ("vel,
ea deficiente, die 2 ianuarii") that colitur does not implement at
all. Independently computed (matched the reviewer's own figure
exactly): 3,619 of 8,417 domain years have no Sunday in 2-5 January,
and colitur emits no Holy Name office whatsoever in any of them -- a
genuine missing II-class feast on 43% of years, not merely an
unnamed generic Sunday the way Holy Family's own pre-task gap was.

Recorded in the register (gitignored, not part of this commit) and
CLAUDE.md's carried-item list; out of this task's own dispatched
scope (Holy Family and RG 112 only), not fixed here.
