Plan: dialog helpers extraction mapping

[SorraTheOrc]

Summary

Planning work item WL-0MO5O06K10079BS7 - extract dialog helpers to shared module.

Work Done

Created mapping of private helpers in DialogsComponent to proposed public API signatures:

1. createList() -> createBlessedList(options) - Creates configured Blessed List
2. createTextarea() -> createBlessedTextarea(options) - Creates configured Blessed Textarea
3. createLabel() -> createDialogLabel(options) - Creates dialog section headers

Documented migration steps and compatibility notes for child work items.

Acceptance Criteria Met

• New module planned with public signatures documented and migration steps outlined
• A mapping is produced showing which helpers in DialogsComponent map to exported functions/classes
• A dependency link to WL-0MNU782BD004HO2W is included in the description

Ready For

• Review of the proposed API signatures
• Decision on API shape (options object vs typed params) - open question
