Subject: [PATCH] Fix Dozzle connection issues and restarts

Root cause: Dozzle was being rate-limited by the Kubernetes API when
fetching logs from many containers. The aggressive 1-second health check
timeouts caused the container to fail probes and restart repeatedly.

Changes:
- Increased all probe timeouts from 1s to 5s to handle API rate limiting
- Increased liveness probe period from 10s to 30s to reduce check frequency
- Increased readiness probe period from 5s to 10s
- Increased startup probe failure threshold from 15 to 20 (60s total startup time)
- Increased CPU limit from 500m to 1000m and request from 100m to 250m
- Increased memory limit from 512Mi to 1Gi and request from 128Mi to 256Mi
- Pinned image version to v10.6.10 instead of :latest

This prevents unnecessary restarts when Dozzle is waiting on rate-limited
Kubernetes API calls, fixing both the initial 503 errors and the connection
drops after prolonged use.

Resolves: DEV-351
