installed app page a nd functionality with fixes to the app catalog page

[usecymk]

Description

Adds full management for installed apps: catalog/installed state, service control (systemd + Docker), logs, config, uninstall, and unit tests for the new behavior.

What was implemented

• Catalog: Installed apps are greyed out and show "Already Installed"; install button disabled.
• Installed Apps page: List of installed apps with Start/Stop, Restart, Logs, Config, Uninstall. Shows status, stats (uptime, memory, CPU), and links to config (domain/port) and app URL.
• Service control: Backend supports both systemd and Docker Compose; service name allowlist; NOPASSWD scripts for uninstall and reading Caddy config (rm-service-dir.sh, read-caddy-config.sh).
• APIs: Service status, logs (GET .../logs?tail=200), stats, config (parsed domain/port), and uninstall (POST .../uninstall with service_name, remove_volumes).
• Deploy: ALTSUITE_DEPLOY_DIR for script path; install copies helper scripts; sudoers updated for the new scripts.
• Jitsi Meet: Added to allowed services (backend, deploy scripts, frontend SERVICE_NAME_BY_APP).
• Unit tests: Go tests for parseCaddyConfig, getDeployDir, and config handler (400 for invalid service name); frontend tests for Installed page (loading, empty state, controls, logs panel, config panel, uninstall flow).

Changes Made

• Backend (api/): privileged.go – service control, logs, stats, config, uninstall, getDeployDir, parseCaddyConfig; main.go – handlers for logs, stats, config, uninstall; privileged_test.go, main_test.go – new tests.
• Deploy: rm-service-dir.sh, read-caddy-config.sh; allowlists in both; install.sh copies scripts; build.sh chmod +x; altsuite.sudoers entries for scripts.
• Frontend: Installed page with status/stats, Logs/Config panels, Start/Stop/Restart/Uninstall; catalog installed state styling; api.ts – getServiceLogs, getServiceStats, getServiceConfig, uninstallService; __tests__/InstalledPage.test.tsx.

Testing

• Tested locally
• Added/updated unit tests (Go + frontend)
• All tests passing
