docs(flomni): document "Load into editor"

User manual: new paragraph in the queueing section explaining the

AI_docs: plan section 6.8 records the design (not a third write path,

_enter_edit_mode_with() refactor; GUI test checklist gets section 6d
(test steps 42-47) and a new section 1 item 11, with the status line
updated to flag 6c/6d as not yet clicked through.

 In addition to tomogram jobs, the same queue can hold **command jobs**: an ordered
