[DX] Enhance Command Palette with Global Navigation and Actions

[emdevelopa]

Description

The CommandPalette is currently underutilized. It should allow users to perform common tasks quickly from anywhere in the app.

Requirements and context

• Add quick actions for "Create New Payment", "Copy API Key", and "Toggle Theme".
• Enable navigation to all high-level routes (Dashboard, Settings, Docs).
• Implement fuzzy search for actions and help topics.

Suggested execution

1. Update the actions list in CommandPalette.tsx.
2. Hook into existing global states (like Theme or Auth).

Test and commit

• Verify keyboard shortcut (Cmd+K) opens the palette.
• Test each action to ensure it triggers the expected behavior.

Guidelines

• Keep the palette focused and fast.
• PR description must include: Closes #[issue_id]

Complexity: Medium (150 points)
