Add Homepage dashboard + dual-export OpenCode traces

Homepage as the front door: single page at framework:7575 with one tile
per service, live widgets where the upstream supports it (Ollama loaded
models, container state via docker.sock, etc.), bookmarks for reference
docs. Config files are pyinfra-managed — source of truth lives in
compose/homepage/, sync by editing there and re-running ./run.sh.

OpenCode plugin now dual-exports spans to Phoenix and OpenLIT in
parallel. Phoenix remains the per-trace waterfall view; OpenLIT picks
up the same data for fleet-level metrics. Each destination has its own
batch processor so a hiccup at one doesn't block the other.
