Subject: [PATCH] fix(telegram): add debug log at startup probe success

Add a debug-level log line confirming when the startup probe succeeds
and the main long-poll loop is entered. Aids diagnostics when
troubleshooting persistent 409s (e.g. from an external competing poller).

Note: persistent 409 despite the startup probe and 35s backoff indicates
an external process is actively polling the same bot token from another
host. In that case, rotating the bot token via @BotFather is the fix.
