Add volume path and clear subcommands

[gtsiolis]

This will add lstk volume command group with two subcommands:

1. lstk volume path: prints the resolved volume directory path for each configured emulator
2. lstk volume clear: removes all data from emulator volume directories to reset cached state
   • volume clear asks for interactive confirmation by default; requires --force in non-interactive mode
   • volume clear supports --container to target a specific emulator (e.g., --container localstack-aws)

volume path	volume clear
