VJ Pixel 3571118218 fix(agent): run init-time fallback for ANY exhausted primary provider
The #17929 init-time fallback block was nested inside the
'_explicit not in {auto, openrouter, custom}' guard, so an exhausted
openrouter credential pool skipped fallback_providers entirely and
AIAgent.__init__ raised 'No LLM provider configured' — surfacing on
Telegram only as the generic 'unexpected error' message.

2026-08-23 outage (~22:09-23:50, 60 occurrences incl. a cron job):
single-entry openrouter pool hit daily free-tier quota; chain had a
healthy local Ollama entry that never got tried because provider was
the default 'openrouter'.

Un-nest the block so any primary without usable credentials walks the
chain before failing; providers explicitly chosen by name keep their
dedicated missing-key diagnostic when both primary AND chain fail.
Regression tests cover the openrouter-exhausted path both with and
without a usable chain entry.
