fix(dashboard): return 404 for event streams of unknown projects

Browse Source 
An SSE subscription with a nonexistent projectId (stale client tab, e2e fixture
page using projectId "fixture") surfaced the PG startup-factory construction
chain as a 500 on every poll, filling operator logs with alarming
"failed to construct TaskStore" errors. Map project-not-found to a clean 404,
matching the project routes' existing handling.

summary: Dashboard event streams for an unknown project now return 404 instead of logging a 500 server error.
category: fix
dev: `/api/events` maps project-not-found store-resolution failures to 404 with a clean message; stale client tabs and e2e fixture pages no longer fill operator logs with startup-factory construction errors.
