Add sudo option to active session commands

[bifrost0x]

Summary

• add an optional "Insert with sudo" checkbox to the active-session command launcher
• preserve exact command insertion without Enter and avoid duplicate sudo prefixes
• expose a server-resolved sudo variant for command sets so existing validation and chaining rules remain authoritative
• update styling, translations, cache versions, and regression coverage

Why

Validation
