Merge pull request #70 from CoMPaTech/upd

## Bug Fixes

Improved authentication handling (cookie/CSRF tracking) and clearer error mapping for auth failures, timeouts, and invalid responses.

## Refactor

Unified request flow for consistent authenticated access across status, stakick, provmode, warnings, progress, download, and install.
Login now raises on failure and no longer returns a boolean.

## Tests

Added focused request-flow tests; several legacy tests adjusted or skipped.
