feat(apiserver): move apiserver to registry and make it configurable (#12493)

#### Description

- Make server port configurable so multiple instances can be started for
agentic development and testing.
- Add `make go-stop` to make it easier to restart server by agents. It
does a graceful stop to allow the Prometheus metrics exporter port to
shutdown otherwise that port remain occupied.
- Add make target for generating the OpenAPI specs.
- Documents the above in `docs/contributing/development.md` under "How
do I run more than one instance?", including `make go-stop` in the basic
backend flow.

+- When making Go changes, always ensure they follow the contributing guildelines in [`docs/contributing/go/`](../../docs/contributing/go/).
+- Look for existing patterns in the codebase for any change before implementing the changes.
+- If any API contract is modified, generate the OpenAPI specs with `make gen-openapi-specs`.
+- Always keep the OpenAPI spec generated in a separate commit, so the whole commit can be dropped in case of conflicts during merge. Do not try to resolve conflict in generated files, instead just generate them again.
+- Avoid breaking function calls unncessarily into multilines for couple of arguments.
+- Try to keep most computational only logic in types package itself related to a domain type, use modules as the orchestraction layer cordinating different layers and all db queries in store layer. Check the serviceaccount modules for inspiration when confused.
+- When defining types, keep the structure of file to have any constants and variables first, then exported types and exported methods and then finally the unexported types and methods.
+- Never import types or other modules in migration files, duplicate the required type or method to keep migration free from changes.
+- Always run the gofmt tool for formating beforing commiting any changes.

+
+Handy when you keep several branches checked out as separate git worktrees. Every port

+
+```bash

+SIGNOZ_SQLSTORE_SQLITE_PATH=/path/to/main/sqlite.db \
+SIGNOZ_INSTRUMENTATION_METRICS_READERS_PULL_EXPORTER_PROMETHEUS_PORT=9091 \
+make go-run-community
+```
+
+| Variable | Default | Why you'd change it |
+| --- | --- | --- |
+| `SIGNOZ_APISERVER_ADDRESS` | `0.0.0.0:8080` | Address the API server listens on |
+| `SIGNOZ_SQLSTORE_SQLITE_PATH` | `signoz.db` in worktree | To reuse same database |
+| `SIGNOZ_INSTRUMENTATION_METRICS_READERS_PULL_EXPORTER_PROMETHEUS_PORT` | `9090` | Bound by the Prometheus metrics exporter on startup |
+
+Point the frontend at whichever backend you want, in `frontend/.env`:

+```env
+VITE_FRONTEND_API_ENDPOINT=http://localhost:8081
