Implements upstream tickernelz#118 and tickernelz#126. An IdC account has two regions: the OIDC region that issued the SSO session and refresh token, and the service region where the Q Developer profile lives. The sync layer set both from the profile ARN, and token.ts builds the refresh URL from oidcRegion — so any account whose Identity Center and profile differ refreshed against an endpoint that never issued the token. The first hour works, then every refresh 400s with 'Invalid token provided'. Upstream confirmed by probing both endpoints. Prefer the device registration's region, then the session's, then the profile's, validating rather than normalising so an unrecognised value falls through instead of silently becoming us-east-1.

Fix for token refresh issue for when the Q profile and Identity Center are in different regions. Here the refresh reaches a regional endpoint that never issued the device registration and fails with HTTP 400 Invalid token provided. As such, tokens last an hour, so sessions start fine and break mid-session.
syncFromKiroCli sets oidcRegion = serviceRegion, where serviceRegion is derived from the Q Developer profile ARN. refreshAccessToken then POSTs the Identity Center refresh to https://oidc..amazonaws.com/token.
isValidRegion is used rather than normalizeRegion because the latter returns us-east-1 for unrecognised input, which would substitute a wrong region instead of falling back.
region still comes from the ARN, so the q..amazonaws.com inference endpoint is unchanged.
