feat(creator-studio): full pay settings and paid resources in the publish drawer

The drawer only had a pay toggle and one bare price field, so several
options from the front-submit pay card could not be set at all.

- New PayPanel mirrors the front-submit card: cash / points segment
  (points only when the site has credits enabled), price or points with
  the currency suffix, and VIP prices. VIP fields render only when the
  site asks for manual VIP pricing and the level is enabled, and now
  submit vip1_points / vip2_points as well.
- New ResourceDialog restores "添加资源": download URL with an attachment
  picker, resource note (extraction code), copy name / value, custom
  button label and button style swatches. Pasting a net-disk share link
  splits the URL and the extraction code.
- pay.ts sends every download display field and tags net-disk links.
- CreatorRest exposes vipManual / vip*Enabled / vip names / pointsEnabled
  / downloadClasses / currencySymbol, and the readback carries
  extractCode / copyKey / copyVal / class / attachmentId.
- Fixes an existing data loss: snapshot_from_payload dropped copy_key,
  copy_val, class and attachment_id, so approving a revision erased them.

Files split to stay within budget: publish-drawer 332 lines, pay-panel
343, resource-dialog 254. 886 widget-system tests pass.
