Use CV_PARSE_USE_MOCK env var and restrict mock CV parsing to test environments

[dogussyaman]

Motivation

• Remove the hardcoded mock toggle so real OpenAI parsing is enforced in non-test environments.
• Allow tests to opt into mock parsing via an environment flag while preventing accidental mock usage in production.

Description

• Replace the USE_MOCK_DATA constant with a useMockData flag derived from CV_PARSE_USE_MOCK and a test-environment check against NODE_ENV/DENO_ENV in supabase/functions/cv-process/index.ts.
• Gate mock data to only be used when CV_PARSE_USE_MOCK is set to true and the runtime is a test environment, otherwise run the real OpenAI parsing flow.
• Update the console message when using mock data to clarify it is for tests only.
• Document the new environment variable CV_PARSE_USE_MOCK in README.md.

Testing

• No automated tests were run for this change.}
