ui: rename the SCP81 script templates to Explore ISD / Delete AID (v3.1.3)

'Explore' and 'Delete' were ambiguous next to the other SCP81 actions.

- template selector: Explore -> Explore ISD, Delete -> Delete AID (EN/RU);
- a new Explore script is named 'Explore ISD'; the Delete template keeps
  its count-based name (e.g. 'Delete 2 AIDs');
- new scriptKindLabel() maps the stored kinds (unchanged:
  explore/delete/install/empty, so existing localStorage scripts keep
  working) to those labels and is now used for the scripts table kind
  column, which used to print the raw lowercase kind untranslated;
- docs: help EN/RU, README/RUS, docs/api.md examples, AGENTS;
- sw.js simple-v238.
