openclaw config-gen.py: api-key mode model IDs probably have a wrong date suffix

config-gen.py line 68 uses claude-sonnet-4-6-20260514 and claude-opus-4-6-20260514. Other parts of the same file use claude-sonnet-4-6.

As far as we know, the Anthropic IDs for the 4.6 models have no date suffix. Not verified against the Anthropic docs. Please check the IDs before a fix.

Found by a static read of the code at commit 1f66a8f. The code was not run.
