docs(link): the catalogue is real, and UOFiddler's last job is gone (Phase 3)

Phase 3 is built and walked on a live shard. What the walk measured, and the
two places the design of record needed correcting:

§8.1, new: the catalogue is 787 exactly as §4.8 predicted, and the whole scan
of bodies 1-2047 takes 734 ms cold -- so the wall-clock paging §11 designed
never fires on this client. Every §4.8/§5.2 prediction held when the bytes were
rendered and LOOKED at: 320, 607, 608 and 666 come back absent rather than as
another creature's picture, and the direction split is 783 at index 1 against 4
at index 0 -- four player bodies, not six.

44 of the 787 hashes are shared by two or three bodies, which is the exact
signature of the wrong-picture bug, so it was chased rather than assumed. It is
the client's own Body.def aliasing (83 {1}, 84 {1}, 106 {12, 59}), and the check
that settles it is at the source: Translate(ref body, ref hue) rewrites `body`
only when bit 31 is set, unlike the one-argument overload -- and ResolveAnimation
calls that same two-argument overload, so validator and decoder resolve the
identical record.

§12.1, new: **§12 is right about the outcome and wrong about the mechanism.**
`shard_spawn_creatures` is emptied and refilled by every atlas refresh, and a
refresh runs on every boot -- so an imported filename written to that row is
destroyed by an ordinary re-parse of the ServUO tree, and the next Update finds
the client files unchanged and never restores it. Three tables outside that
blast radius, and the atlas import re-derives `art` on the way past.

§14: **§16 listed phase 3 as servuo-plugins + module-uo and that was wrong.**
web.rs routes every command explicitly, so `link` is in the phase. Corrected in
both places.

UOFIDDLER.md is DELETED, two phases earlier than §9.1 predicted -- creature art
was the only thing still on it. SPAWN_ATLAS.md §Artwork is rewritten around the
import, keeping the operator's own map as the thing that wins; the module's
SCHEMA.md gains the three tables and API.md the two admin routes.
