John O'Keefe 8d5d8ac2d7 refactor(frontend): flowbite-svelte v1 APIs, bindings-aligned store types
flowbite-svelte v1 turns components into runes: on:click on
components becomes onclick props (native elements keep on:), Modal
footers become {#snippet footer()}, Button["color"] indexing becomes
the exported ButtonProps type, and slate is gone from the color
union so the datepicker greys map to gray.

Stores now use the generated bindings models (what the Go backend
actually returns) instead of hand-written shapes that drifted from
them - nullability of genres/tags/mediaList included. That single
move clears most of the newly surfaced type errors, including the
optional episodes/nextAiringEpisode cluster. The rest is strictness
debt the old red check masked: definite-assignment on
subscribe-fed lets, null guards on querySelector/match results and
date parsing (two of which fixed latent throw-on-garbage paths),
aria-labels on icon-only buttons, the completed default-data
literal, and a shared flex centering context for the detail poster
column so poster and stars align by construction at every width.
