feat(editor): add WPSP (Player Spawn Profile) open catalog format

Open replacement for AzerothCore's playercreateinfo SQL table
plus the per-class/race starting fields in CharStartOutfit.dbc.
Defines the initial state for a newly created character: starting
map / zone / position / facing, bind point (Hearthstone
destination), up to 4 starting items with counts, and up to 4
starting spells.

One entry per (race, class) combination — a Human Warrior spawns
at Northshire Abbey with a Worn Shortsword and Heroic Strike
already learned, while an Orc Hunter spawns in Valley of Trials
with Aimed Shot and a starter rifle. Death Knights have their
own preset spawning at lvl 55 in Acherus, the Ebon Hold.

The race+class fields are bitmasks (mirroring WCHC layout) so
one profile entry can cover multiple class/race combinations
that share starting state. findByRaceClass(raceBit, classBit)
is the engine helper used by character creation.

Cross-references back to WCHC (race/class bit layouts), WMS (map
ids), WIT (starting item ids), and WSPL (starting spell ids).

Three preset emitters: --gen-psp (5 Alliance combos covering
each starting zone from Northshire to Ammen Vale), --gen-psp-horde
(5 Horde combos from Valley of Trials to Sunstrider Isle),
--gen-psp-dk (2 DK combos at lvl 55 in Acherus with Death Coil /
Plague Strike / Death Grip starter loadout).

Validation enforces id+name+race+class+startingLevel presence,
no duplicate ids; warns on (0,0,0) spawn (uninitialized entry),
item id/count mismatch (granted item without count or vice versa),
startingLevel > 80 (above WotLK cap), and Death Knight class
with startingLevel < 55 (DKs canonically start at 55).

Wired through the cross-format table; WPSP appears automatically
in all 12 cross-format utilities. Format count 76 -> 77; CLI flag
count 951 -> 956.
