Subject: [PATCH] Increase required flit_core version to 3.11

Needed since Flask 3.1.1 after having set the "license" keyword to an
SPDX license expression. Avoids this possible build error:

  flit_core.config.ConfigError: license field should be <class 'dict'>, not <class 'str'>

Fixes: 0109e496f ("use uv").
