Add static/services.ini as a reference example, and update both the
article draft and working notes with the discovery: placing this file
in the terminal installation's config folder auto-registers the
compiled service, removing the manual Navigator step. Note explicitly
that the file is undocumented (UTF-16LE, absent from the official
config file listing) and likely the terminal's own internal
serialization of Navigator-added services.
Add a section explaining services as an MQL5 program type (single
OnStart handler, no chart binding, per-instance thread, survives
account switches) and a section on the stop grace period, tying the
documented 3-second IsStopped() timeout to the service's jittered
Sleep(). Cite official docs for DatabaseBind indexing, transaction
speedup, and DATABASE_OPEN_COMMON; add a references section.
