fix(env): simplify self-host runtime defaults

[izadoesdev]

SELFHOST=true keeps omitted service URLs local, lets queues reuse REDIS_URL, and prevents server product telemetry from starting, even with copied Databuddy keys. Explicit URL overrides still win; hosted defaults remain unchanged.

Adds explicit workspace dependencies for the existing environment helper. No new runtime settings or schema changes.

Validation: 30 focused environment, browser-config, Redis, and telemetry tests pass. The browser regression verifies both mode values, local versus hosted production URLs, and preserved pixel behavior. Root lint (22 policy checks), all 33 typecheck tasks, frozen install, and all 29 pre-push tasks pass.

Depends on #816 for exposing self-host mode to the dashboard browser bundle and #806 for SELFHOST forwarding through Turbo; both are merged. Rebased directly onto staging containing #816. Preserves the existing Docker build argument and browser-mode forwarding; complements the short environment template and Compose setup in #804.

The PR appears safe to merge with no outstanding correctness, security, or repository-rule findings.

Summary

This PR makes self-host mode consistently select local service defaults, reuse the shared Redis connection for queues, suppress server product telemetry, and propagate canonical self-host state into the dashboard browser bundle.

• Explicit URL overrides continue to take precedence, while hosted production defaults remain unchanged.
• BullMQ falls back to REDIS_URL only in self-host mode.
• Dashboard build configuration forwards a canonical browser mode value and tests URL and advertising behavior in both modes.
• AI telemetry client creation is disabled in self-host deployments.
• Required workspace dependencies and lockfile entries are included.

@greptileai review this. Final head ebe714f is rebased onto staging containing merged #816 and #806. Browser mode forwarding is now present and the existing Next regression verifies self-host and hosted production URL defaults plus signup tracking. SDK mocks use exported SDK types. The external Docker commit is preserved. All 30 focused tests, lint, 33 type tasks, and 29 pre-push tasks pass.

@greptileai review this. Final head 218cb66 adds only --isolate to the existing Links test command, fixing the Linux CI ordering conflict where a route test replaced the shared environment module before producer tests imported readBooleanEnv. All 27 Links tests and all 29 repository test tasks pass. The previously reviewed runtime changes and merged dependency base are unchanged.
