refactor: consolidate tabs — remove standalone Logs and Config tabs

Logs functionality already exists in Runtime tab (AgentHealth/AgentInstance).
Config functionality moved to Deployments tab ConfigSubTab.
Old routes redirect to /runtime and /apps respectively.
Navigation links updated throughout.
