chore(ai-config): switch default gptel backend to ChatGPT / gpt-5.5

Two places set the default backend + model on gptel initialization
-- `cj/ensure-gptel-backends' (the lazy-init fallback) and the
`use-package gptel :config' block (the eager-set after initialization).
Both now pick the ChatGPT backend with `gpt-5.5' instead of Claude
with `claude-opus-4-7'.
