docs: Migrate tutorials content to wiki and archive repo.

[nedseb]

Description

Once the restructuring is complete (steami_screen in micropython-steami-lib, tools in micropython-steami-tools), the tutorials are pure pedagogical content that belongs in the wiki alongside other documentation.

Tasks

• Migrate all 15 tutorials to the wiki (one page per tutorial, with code snippets and screenshots)
• Organize wiki navigation (by difficulty, by sensor, by widget)
• Include screenshots from micropython-steami-tools mockups
• Link to driver documentation in micropython-steami-lib
• Archive this repo once migration is validated

Blocked by

• refactor: Remove library and tools after migration to dedicated repos. #1 — Cleanup after steami_screen/tools migration (must be done first)
• refactor: Remove lib/ directory after steami_screen migration. #2 — Remove lib/
• refactor: Remove sim/ and tools/ after migration to steami-tools. #3 — Remove sim/ and tools/
• refactor: Update tutorial imports for frozen steami_screen. #4 — Update tutorial imports

Notes

The tutorials should be validated on hardware with the frozen firmware before migrating to the wiki. The wiki format should include:

• Screenshot (from mockups)
• Full source code (main.py)
• Explanation of widgets and sensors used
• Link to driver API documentation
