rename OTAMan → SIMple (v2.3.0)

- package pysim_otaman_server → pysim_simple_server; distribution and
  console script pysim-otaman-server → pysim-simple-server
- PWA branding SIMple: title, header, manifest, help EN/RU, GitHub links
- localStorage keys otaman_* → simple_* (clean break, no migration)
- export filenames simple-cards.json / simple-custom-files.json
- service worker cache simple-v189
- README/docs/setup/start scripts updated; no 'otaman' left in the tree
