fix: validate AWS SSO session before launching Claude for Bedrock Profile auth
When using AWS Profile auth (SSO) with Bedrock, expired SSO sessions
caused Claude Code to spin indefinitely. Three root causes fixed:

1. Mount host .aws at /tmp/.host-aws (read-only) and copy to
   /home/claude/.aws in entrypoint, mirroring the SSH key pattern.
   This gives AWS CLI writable sso/cache and cli/cache directories.

2. For Bedrock Profile projects, wrap the claude command in a bash
   script that validates credentials via `aws sts get-caller-identity`
   before launch. If SSO session is expired, runs `aws sso login`
   with the auth URL visible and clickable in the terminal.

3. Non-SSO profiles with bad creds get a warning but Claude still
   starts. Non-Bedrock projects are unaffected.

Note: existing containers need a rebuild to pick up the new mount path.
