fix(codecov): align flag declarations with workflow uploads

The codecov.yml flags (python, rust) did not match the flags used by
test.yml (api, curator, common, dashboard, explore, graphinator,
schema-init, tableinator, extractor). Undeclared flags get no carryforward
or path configuration, causing upload errors.

- Replace python/rust flags with the nine service flags actually uploaded
- Add api, curator, schema-init components (were missing from the
  component breakdown)
- Keep e2e-* flags unchanged (correctly declared and used by e2e-test.yml)
