Proxy debug metrics and push access permissions

Daytona 0.187.0 tightens who can push snapshots and images by requiring explicit write permissions on push access endpoints, and improves observability with a debug metrics server on the proxy.

Features

Dashboard: limits classes tabs

Docs: add android and linked sandboxes

Proxy: expose debug metrics server

Fixes

API: require a write permission for temporary push access endpoints

API: redirect root requests to /dashboard

CLI: drop redundant BucketExists probes in minio client

Chores

sync go.sum for v0.186.0

split publish jobs per project

Go SDK: bump to v0.187.0

Breaking Changes

API: GET /object-storage/push-access and GET /docker-registry/registry-push-access now require the caller to hold either write:snapshots or write:sandboxes (previously no specific permission was required). Migration: grant write:snapshots or write:sandboxes to API keys that push snapshots or build declarative images with a local context.
