[Feature]: Storage breakdown per media type / library

[albinmedoc]

Describe the feature

Expose total storage size broken down per media type (Movies / TV Shows) and/or per library. Today the Library Overview only shows a single aggregated "Total Size" (e.g. 197.4 TB). It would be great to see how that number is distributed — for example:

• Movies: X TB
• TV Shows: Y TB
• Per library e.g.
  • Movies: X TB
  • Movies 4K: X TB
  • TV: X TB
  • TV 4K: X TB
  • Anime: X TB

Ideally this should be available both:

• Via the API (primary need for me) — so the data can be consumed by external dashboards, alerts, and automations.
• In the UI — as an extra stat card on the Library Overview and/or a small breakdown chart (pie/bar) next to the existing Library Growth chart.

What problem does it solve

The current single "Total Size" number makes it hard to understand where storage is actually going and to plan capacity. When libraries grow at different rates (e.g. 4K movies vs. TV episodes), it's valuable to see the split so you can make informed decisions about pruning, quality profiles, or adding storage. Pulling it from the API also makes it possible to integrate into existing monitoring (Grafana, Homepage, etc.) without scraping the UI.

Examples or references

Tautulli shows library cards with per-library size. Radarr/Sonarr expose per-series/per-movie sizes via their APIs which can be aggregated per root folder. A similar breakdown in Tracearr — exposed cleanly via API and visualized in the UI — would be ideal.

Platform

• Web Dashboard
