feat(honorific): render glow outline as opt-in (gradient deferred)

Honorific's TitleData carries Glow / Color3 / GradientColourSet /
GradientAnimationStyle beyond the Title + Color we parsed in Cycle 1.
The DTO now mirrors all four so the JSON roundtrip doesn't silently
drop fields.

Rendering for v1.4.7 covers Glow only: when Config.ShowHonorificGlow
is on and the title has a Glow colour, the chat header title gets an
8-direction ±1px draw-list outline pre-pass in the glow colour at 0.4
alpha, then the primary text on top.

Gradient (Color3 / GradientColourSet / GradientAnimationStyle) is parsed
and stashed for a later cycle — porting the full animation needs
Honorific's hardcoded Pride-palette list and GradientSystem.cs (or an
upstream IPC PR exposing the resolved frame colour). Tracked as
"Honorific Full Gradient Port" in the vault backlog.

ShowHonorificGlow defaults OFF — keeps v1.4.6 visuals untouched and
dodges per-frame DrawList overhead on low-end hardware. Tooltip flags
the gradient deferral so users aren't surprised by static rendering.
