Lukas Brübach 7d04c50f2c [PictureLoader] Add user-configurable per-host request caps
Picture downloads were throttled to a uniform 10 requests/second per host
with no way to tune a specific server. A rate-limited API host (Scryfall
caps at 10 req/s) can trip 429s during bursts, and CDN hosts with no rate
limit were throttled needlessly.

Introduce developer-owned per-host caps that users can only ever lower,
never raise, exposed in the download settings page:
- DownloadSettings::DEVELOPER_HOST_CAPS sets the ceiling per host
  (api.scryfall.com 9, cards.scryfall.io unlimited, others 10).
- A new hostRequestLimits setting stores user overrides in downloads.ini;
  clampHostRequestLimit() bounds them to [1, devCap] so a user can reduce
  api.scryfall.com to 5 but never raise it above 9.
- The picture worker seeds, halves on 429, and recovers its sustained
  per-host allowance against the effective ceiling instead of the global
  maximum, and skips per-host accounting entirely for unlocked hosts
  (cards.scryfall.io) while global pacing and 429 backoff still apply.
- The deck editor settings page gains one spinbox per known host, each
  clamped to its developer cap.
