docs(todo): #60 — add channel-profile category tabs (Videos/Audio/Live/Shorts)

Expands the Audio-tab item with a channel-profile tab strip carrying the same
media categories (Videos / Audio / Live-Streams / Shorts), each its own lazily-
loaded per-tab playlist, empty categories hidden, mirrored on the sidebar. Adds a
shared media-category resolver (video|audio|live|short from kind + imeta m + t)
used by both the sidebar feeds and the channel tabs — the natural home for the
#17 unified media grid. Cross-refs #16 (NIP-53 live + kind-22 shorts) / #17.

+- [ ] **Channel-profile category tabs (requested 2026-07-09).** The channel profile

+      neat and self-explanatory instead of mixing everything into one grid:
+      - **Videos** (current default — kind 30078 video / NIP-71 21+34235),
+      - **Audio** (audio-only notes — podcasts / music; the #60 audio player),
+      - **Live** / **Streams** (NIP-53 kind 30311 — see #16; show live now + past),
+      - **Shorts** (NIP-71 kind 22 short-form vertical — see #16).
+      Each tab is its **own category playlist** that only loads/renders when that tab
+      is selected (lazy per-tab fetch, no cross-contamination — the audio guard keeps
+      Audio out of Videos and vice-versa). Only show a tab when the creator actually
+      has content of that type (hide empty categories). Mirror the same tab set on the
+      main feed/sidebar so the sidebar category ↔ channel tab stay consistent.
+- [ ] **Shared category model:** define one media-category resolver
+      (`video | audio | live | short`) derived from kind + `imeta m` + `t` markers,
+      used by BOTH the sidebar feeds and the channel tabs, so a note lands in exactly
+      one category everywhere. This is the natural home for the #17 unified media grid.
