feat: add accessible tooltips to all editor controls

[jaygaikar-09]

Description

Added accessible tooltips to all editor controls to improve usability and onboarding for first-time users.

Implemented a lightweight reusable Tooltip component with support for:

• hover interactions
• keyboard focus accessibility
• long-press support on touch devices

Tooltips now explain editor settings, constraints, and quality/performance tradeoffs directly within the UI.
