test(AdvancedSettingsPanel): add massive scaling tests

[REHAN-503]

Description

Fixes #4336

Added a dedicated massive scaling test suite for AdvancedSettingsPanel covering extreme configuration values and high-volume user interactions.

What was added

• Added AdvancedSettingsPanel.massive-scaling.test.tsx
• Verified rendering with maximum supported width and height values
• Tested repeated width updates across large value ranges
• Tested repeated height updates across extreme bounds
• Validated grace slider behavior across its full supported range
• Simulated high-volume mixed interactions to ensure callback integrity and component stability

Why

This issue focuses on ensuring that the component remains reliable when handling large configuration values and frequent updates. The tests exercise the real component and verify that state-change callbacks continue to behave correctly under scaling-related scenarios.

Scope

• Added isolated Vitest coverage for massive scaling scenarios
• No production code changes
• No UI or visual modifications

Pillar

• 🎨 Pillar 1 — New Theme Design
• 📐 Pillar 2 — Geometric SVG Improvement
• 🕐 Pillar 3 — Timezone Logic Optimization
• 🛠️ Other (Testing)

Visual Preview

N/A — Test coverage only. No visual changes.
