fix(email): open settings after OAuth callback (#5803)

The version pattern in _anthropic_rejects_temperature() required a minor
component, so major-only ids like `claude-opus-5` never matched and the
guard reported that the model accepts `temperature`. Anthropic rejects the
field outright on Opus 4.7+, so every such call returned HTTP 400 and the
stream aborted with zero tokens ("the model returned an empty response").

Make the minor optional and read a missing minor as `.0`. The major is also
capped at 1-2 digits with a no-trailing-digit lookahead, mirroring the
minor: once the minor is optional, a greedy major would swallow the date in
`claude-3-opus-20240229` and read it as version 20240229, dropping
temperature from a model that accepts it.

Fixes #5753
