Add channel token support to importchannel management command
Implements support for using channel tokens in addition to channel IDs when importing channels via the importchannel command, addressing issue #3733. Key features: - Token resolution via channel lookup API (works with Studio or any Kolibri instance) - Automatic detection of tokens vs channel IDs using UUID validation - Interactive multi-channel selection when token resolves to multiple channels - Non-interactive mode shows error with all channel options - Comprehensive error handling with user-friendly messages - Full backward compatibility with existing channel ID usage Implementation details: - Added resolve_channel_token() utility in paths.py using duck typing - Returns tuple of (channel_id, all_channels) for flexible handling - Command detects TTY to determine interactive vs non-interactive mode - Interactive mode prompts user to choose from numbered list - Non-interactive mode fails with clear error listing all options - Only network subcommand supports tokens (disk requires UUIDs) Error handling improvements: - JSON parse errors caught with helpful messages - Network failures, invalid tokens, malformed responses all handled - Validates all channels have IDs before returning - Clear error messages guide users to resolution Test coverage: - Token resolution (single and multiple channels) - Invalid JSON responses - Missing channel IDs - Default and custom baseurl - All error paths covered Fixes #3733
