Placard 1.0.0 — bake library names onto backdrops

Jellyfin 10.11 plugin: a scheduled task that labels each library card with the
library name over a representative backdrop (Noto Sans, centered, soft shadow),
matching Jellyfin's default cover style. Supports source rules (top-rated /
random / newest) and per-library pinned sources. Sets images via the internal
provider API so the home-screen view cache updates without a server restart.
