castbar: mark a cast that none of your interrupts can stop

ClassicAPI carries notInterruptible on C_Spell.UnitCastingInfo (arg 8) and
UnitChannelInfo (arg 7); both call sites already stepped over it positionally.
The target, focus and nameplate bars now paint it.

There is no shield art to hang on the icon -- this client ships three
CastingBar textures (Border, Flash, Spark), and Blizzard's shield arrived in
3.x -- so the state is carried by color instead: the bar and the icon's
border both take a new appearance.castbar.shieldcolor, which keeps it legible
on a bar configured without an icon. One api helper paints both so the two
modules cannot drift apart on it.

Dusty rose (.8,.45,.45) rather than a steel grey. Grey is the retail
convention, but pfUI's casting color is already a near-grey pale blue, so the
two separated on brightness alone and washed out against the bar texture. The
rose sits above failcolor in luminance and well below it in saturation, and
the two are further told apart by motion: a failed cast flashes the bar full
and fades, a shielded one fills normally and tints the icon border, which
failcolor never touches.

Not on the player's own bar. The flag is measured against the reader's own
interrupts and silences, so on your own cast it answers a question nobody
asked.

Stamped once at cast start, with the rest of the cast data, rather than
re-polled. ClassicAPI evaluates lazily from the caster's live auras but does
not yet fire the 3.3.5 UNIT_SPELLCAST_INTERRUPTIBLE / _NOT_INTERRUPTIBLE
change events, and polling per frame would undo the event-driven rework these
bars just got -- so a caster who bubbles mid-cast keeps the bar it started
with until the next one.

Two limits worth knowing when it stays dark. The value is relative to your own
kit -- with no interrupt and no silence known it is never reported, whatever
the cast -- and a creature's built-in interrupt immunity lives in
creature_template, which 1.12's SMSG_SPELL_START does not carry, so a boss
with that immunity reads interruptible while your kick still fails on it.
