feat(admin): DB-driven storage sum + grouped error log viewer

Storage:
- The dashboard storage card used to walk Storage::disk('public')'s
  videos / thumbnails / avatars / images directories. NAS is primary
  storage, so for every file that's been pushed-and-purged (most of
  them, per CLAUDE.md), the disk walk reports 0. Replace with a
  DB-driven estimate: SUM(videos.size) for video bytes plus a 120 KB
  conservative per-file estimate × (thumbnails + avatars + banners +
  post images). Fast (3 count queries + one SUM), works regardless
  of local-cache state, and now reflects content that lives on NAS.

Error logs:
- Flat view used to render every line as its own equal-weight <div>,
  so a stack trace of 70 frames buried the next real event. Group
  lines by header: a line that matches .(ERROR|WARNING|INFO|DEBUG|
  CRITICAL|…): starts a new group; subsequent lines belong to its
  stack trace. Each group collapses by default behind a caret the
  admin can expand. Stack-trace lines preserve their natural #0 → #N
  order inside the group even when the file is reversed newest-first.
