bug: coder login --first-user-trial=true unusable in non-interactive environments

[blinkagent]

Current Behavior

Running coder login --first-user-trial=true in a non-interactive script fails with EOF because trial info fields (firstName, lastName, phoneNumber, jobTitle, companyName, country, developers) are only collectible via interactive prompts. There are no CLI flags or env vars to supply them.

Error:

Your Coder deployment hasn't been set up!
> Please enter firstName: error: EOF

--first-user-trial=false works fine since it skips trial info prompts.

Expected Behavior

Add CLI flags and env vars for trial info fields so --first-user-trial=true works in automation. For example: --first-user-trial-first-name / CODER_FIRST_USER_TRIAL_FIRST_NAME, and similar for lastName, phoneNumber, jobTitle, companyName, country, developers.

Steps to Reproduce

1. Fresh Coder deployment with no users
2. Run coder login with --first-user-trial=true and all other first-user flags in a non-interactive script
3. Command fails with EOF at the firstName prompt

Relevant Code

Trial info prompts in cli/login.go L285-L330 are gated behind if trial { with no flag/env var fallbacks. The options set at L446-L482 only has --first-user-trial (bool).
