docs(todo): #60 — "My Videos" → "My Content" with category tabs

Adds the creator-side mirror of the channel tabs: rename the profile-modal
My Videos pane (MyVideosController) to "My Content" with Videos/Audio/Live/Shorts
tabs, each scoping the management rows (edit/delete/mirror/storage) to one
category. Reuses the shared category resolver so items bucket identically on the
owner view and the public channel.
