v1.49.0: content-fit zoom, swipe animation, wording, and the v1.47.0 review

Owner's batch:
- zoom now opens on what is DRAWN (rooms + 5% margin) for spaces with no
  background image; with one the image is the plan and still fits whole. A small
  plan on the square canvas no longer opens as a speck.
- swiping between spaces, and the kiosk carousel, slide sideways; honours
  prefers-reduced-motion.
- the room settings button reads 'Room settings' and lightens on hover.
- 'curation' is filtering everywhere: UI strings, docs, code.

Checked the yard while I was there: its drawing sits off-centre because it was
drawn that way — before the migration x spanned 0.12..0.54 with 0.12 and 0.46 of
margin. The migration added 0.1465 on each side, symmetrically. Content-fit zoom
makes it moot anyway.

From the v1.47.0 review:
- HP-1470-02: the picker let you delete the plan you had just selected — it is
  not in the stored config yet, so the server rightly called it free, and the
  save then stored a url with no file. The button is disabled, and since two
  clients can do this in either order, config/set now verifies every internal
  plan url against the disk under the write lock and answers .
  External and legacy urls are not ours to police.
- HP-1470-01: growth is bounded at the door rather than by deleting old files —
  that mistake cost real plans twice. check_quota refuses an upload that would
  push the store past 256 MB / 200 plans (1 GB / 1000 attachments) or leave less
  than 512 MB free. The plan list is capped at 60 newest with a total, and
  thumbnails load lazily.
- HP-1470-03: picking a saved plan waited for nothing and stored a fallback
  ratio when the signature had not arrived — a square plan came out stretched.
  It waits for the signature, binds the result to the dialog that asked, and the
  dialog preview is signed too.
- report §5: the last lifecycle comments still described age-based collection.

Not released yet — the owner asked for a release once the batch is done.
