Round-1 test feedback + smoke-test script

- API smoke test (server/smoketest.py): stdlib end-to-end check of health,
  projects, SOPs, WPs, the AWP issue gate (409 → 200), status, metrics,
  comments, and cascade delete. Referenced from DEPLOYMENT.md.

SOP config:
- Constraints: fix custom constraints never appearing — renderStandardConstraints
  no longer clobbers state.constraints; customs render in their own list with
  remove buttons; modal gains a free-text "Add" field.
- Sources: add column headers (Data Type / Location-Platform / URL / Notes);
  preset data types are now fixed labels, "Add Source" creates an editable
  custom row.
- Issuance strategy: add a tooltip + worked examples for each option.
- Remove the "Comment submitted" acknowledgement popup (home + suite); keep the
  commenter name between comments.

WP creator:
- Clearing the last open constraint now offers to mark the package Issued and
  scrolls to the status control.
- Form sections are collapsible (click a section heading to fold it).
