fix(export): /export/etherpad honors the :rev URL segment (#7566) 
Fixes #5071. `/p/:pad/:rev/export/etherpad` has always ignored the rev
parameter and returned the full pad history, unlike the txt/html
export endpoints which use the same route but do respect rev. Users
wanting to back up or inspect a snapshot of a pad at a specific rev
got every later revision in the payload instead — both wasteful and
a surprise when the downloaded .etherpad blob contained content that
had supposedly been reverted.

Change:
  - `exportEtherpad.getPadRaw(padId, readOnlyId, revNum?)` now takes an
    optional revNum. When supplied, it clamps to `min(revNum, pad.head)`,
    iterates only revs 0..effectiveHead, and ships a shallow-cloned pad
    object whose `head` and `atext` reflect the requested snapshot. The
    original live Pad is still passed to the `exportEtherpad` hook so
    plugin callbacks see the real document.
  - `ExportHandler` passes `req.params.rev` through on the `etherpad`
    type, matching the existing behavior of `txt` and `html`.
  - Chat history is intentionally left full (it is not rev-anchored).

Adds three backend regression tests under `ExportEtherpad.ts`:
  - default (no revNum) still exports the full history
  - explicit revNum limits exported revs and rewrites the serialized
    head so re-import reconstructs the pad at that rev
  - revNum above head is treated as full history, preventing accidental
    truncation of short pads

Out of scope: `getHTML(padID, rev)` on the API side is already honoring
rev in current code (exportHtml.getPadHTML threads the parameter
through), so the earlier report on that API call appears to be
resolved. This PR does not touch it.
