feat: add persisted logs

[leafty]

Adds support for persisted logs from Amalthea sessions and image builds. When persisted logs are enabled, get logs from the new persisted logs API endpoints and show the logs history.

• Logs are collected from the Loki read API and are stored in the database when attributed to an existing user, session launcher or image build
• Persisted logs for sessions (interactive and jobs) are readable from their owner only
• Persisted logs for image builds are readable by project editors (+repository readers for private image builds)
• Persisted logs are removed once their TTL has expired (set from helm chart values)

Given that persisted logs rely on specific Loki configuration settings, the feature is toggled off by default in the renku helm chart.
