v1.9.21: SCP80 docs as parent section, GP+JavaCard AID labels, UX fixes

Docs:
- SCP80 tab is now a parent section (3) with subsections 3.1/3.2/3.3
- Renumbered sections: Response parser→4, Card reader→5, Server→6, Version compat→7
- Applied to help.html, help-ru.html, README.md, README_RUS.md

C-APDU/RAM form labels (GP + JavaCard terminology):
- AID → Application / Instance AID
- ELF AID → Load File AID / Package AID
- Module AID → Executable Module AID / Applet Class AID

SCP80/RAM explorer labels (GP + JavaCard terminology):
- ISD → ISD (Issuer Security Domain)
- Applications → Applications / Applet Instances
- Executable Load Files → Executable Load Files (ELFs) / Packages
- AID → Application/Instance AID or Load File AID/Package AID (context-dependent)
- Module AIDs → Executable Module AIDs / Applet Class AIDs

UX fixes:
- Delete All button now matches Delete button style (red)
- Explorer results cleared when switching away from Explore Card operation
- KIc/KID dropdowns (index + algorithm) now update when selecting saved card
- Added LANG_RU translations for new labels
