fix: resolve SQLite SQLITE_BUSY write contention in ingestor
Three changes to eliminate concurrent write collisions:
1. Add _busy_timeout=5000 to ingestor SQLite DSN (matches server)
- SQLite will wait up to 5s for the write lock instead of
immediately returning SQLITE_BUSY
2. Set SetMaxOpenConns(1) on ingestor DB connection pool
- Serializes all DB access at the Go sql.DB level
- Prevents multiple goroutines from opening overlapping writes
3. Change SetOrderMatters(false) to SetOrderMatters(true)
- MQTT handlers now run sequentially per client
- Eliminates concurrent handler execution that caused
overlapping multi-statement write flows
Root cause: concurrent MQTT handlers (SetOrderMatters=false) each
performed multiple separate writes (transmission lookup/insert,
observation insert, node upsert, observer upsert) without transactions
or connection limits. SQLite only permits one writer at a time, so
under bursty MQTT traffic the ingestor was competing with itself.
