feat: add Nitter service template

[maebahesioru]

Changes

Adds a one-click deployment template for Nitter, a privacy-focused alternative front-end for Twitter/X. The project has resumed active development (latest commit March 2026).

The template includes:

• nitter (port 8080) — main app
• nitter-redis:6-alpine — cache

nitter.conf is injected via bind-mounted content. Users must provide their own sessions.jsonl (Twitter/X session tokens generated via the included tools/get_sessions.py).
