docs: fix hallucinated URLs + add Browser-Flasher / Local-Web-UI / PWA-Walkthrough
Fixed:
- home-assistant-tanksync → smartghar-homeassistant (real HACS repo)
- @RaviSinghTechposts → @ravis1ngh (real YouTube)
- smartghar.org/products/tanksync → smartghar.org/tanksync
- removed unverified /privacy + /pricing references
Added 3 new pages embedding screenshots already in the main repo:
- Browser-Flasher: WebSerial flasher walkthrough with screenshots
- Local-Web-UI: every tab (Tanks/Devices/Network/System/Cloud)
- PWA-Walkthrough: every PWA screen including light/dark variants
Hardware-Build now embeds all 9 build photos inline.
