[FEATURE] (Mastracode) Add multiline and wrapping support for "Question" input box

[Doddle-BE]

Problem Statement

Currently, when entering a prompt in Mastracode, the "Question" input field only supports a single line of text. This makes it difficult to write structured or longer queries, since text quickly overflows and cannot wrap.

Problem:
When typing a multi-sentence question, the text becomes hidden beyond the viewable area. You have to scroll horizontally to see your full input, which is inconvenient and prone to input errors.

Proposed Solution

• Enable text wrapping within the "Question" input box.
• Allow multiline input (e.g., via expanding textarea or adjustable height).
• Add keyboard shortcuts (Shift+Enter for new line) for usability.

Benefits:

Improves readability and makes it easier to structure complex prompts.
Enhances user experience for those writing longer or formatted questions.
Aligns with common UX patterns across chat-style and coding interfaces.

Environment:

Mastracode version: [0.13.0]
Tool: [Superset]
OS: [MacOS Tahoe 26.3.1]
