Svet Črnil Pomoč Android 2.0.6 (20006)

Display sleep prevention now covers consented preparation, queueing, connection
and ongoing support. It does not depend on an already connected remote peer.
A refreshed 120-second lease survives brief communication delays; cancellation,
completion, service shutdown and lease expiry release it. The OS wake lock does
not turn on a manually switched-off display. No fake taps or global timeout changes.
The generic pink RustDesk mobile scam modal and both callers are removed.
Android screen-capture/accessibility permissions and support consent remain.
Same application ID and release key preserve the existing installation and case.

Regression surface relative to 2.0.5:
- commercial_api.dart: eligibility and bounded lease duration.
- commercial_page.dart: native lease renewal while waiting as well as connected.
- SvetCrnilSessionExperience.kt: matching native lease maximum.
- server_page.dart: remove generic dialog and invoke existing permission path.
- home_page.dart: remove obsolete warning argument.
- pubspec.yaml and source packer: 2.0.6 release metadata.

Rebuild with the 2.0.0 guide and --build-name=2.0.6 --build-number=20006.
Native RustDesk 1.5.0 libraries remain unchanged for ARMv7, ARM64, x86_64.
Physical-tablet validation is separate from build, signing and contract checks.
