fix(ssr): bulk-edit empty-selection 500 + modal-footer EDN leak

- BUG D: clicking "Bulk Edit" with no invoices selected 500'd. selected->ids
  returns nil with no selection, and all-ids-not-locked fed that nil into a
  Datomic `:in $ [?i ...]` query ("Unable to find data source"). Guard the body
  with (when (seq all-ids) ...) so an empty selection yields [] and the modal
  opens cleanly. Verified live: no "Oh, drat" toast, no 500.

- BUG B: modal-footer- called (hx/alpine-appear ...) twice; the 2nd return value
  (an attribute map) landed in child position and rendered as literal EDN
  ({:x-show ...}) in the red error banner whenever unexpectedError flipped true.
  Delete the duplicate. Verified: rendered HTML now has one alpine-appear and no
  EDN-text child. (Pre-existing defect, also present on master.)
