[Feature Request] Expose conditional display and fill-in-blank option settings for base and form commands

Two form capabilities native to Lark/Feishu are not exposed by lark-cli base +form commands, making it impossible to automate certain form configurations at scale. This issue requests CLI or API coverage for:

1. Conditional field display (question visibility rules)
2. Fill-in-blank after option (inline text input attached to a choice)

Lark Base's form view natively supports conditional display (a field can be set to appear only when a preceding single-select field equals a specific value). The official Lark documentation demonstrates exactly this pattern: a free-text "reason" field that appears only when the user selects a negative option.
Lark Survey also supports a "fill-in-blank after option" mode, where a single-choice or multiple-choice question can have an optional text box attached to one or more options, producing a compact, single-question UX for "select + qualify" scenarios.

Start by locating the existing lark-cli base +form commands and their form option handling. Compare that implementation with the two capabilities described in the issue and determine whether the required Lark API coverage is available. Done means users can configure conditional field display and fill-in-blank options through the relevant CLI or API commands.
