[Studio][Language Understanding] Improve the Intents header and quick filters #2036

@svndrine

Issues identified

• The header does not make good use of space and does not help users quickly prioritize what needs attention
• Quick filters are missing, making it harder to navigate intents by status or category
• The header does not highlight key information clearly.
• There is no clearly visible action to create a new intent directly from the header

Suggested changes

1. Add summary information in the header

Display key figures directly in the header to help users quickly understand the current state of the section.

Example:
128 intents • 12 incomplete • 8 without story

2. Add a clearly visible action button

Add a visible button in the header so users can create a new intent more easily.

Example:
+ New intent

3. Add quick filters

Add quick filters to make the list easier to browse by status or category.

Examples:
All / Incomplete / No story / With entities

4. Improve overall header clarity

Reorganize the header so the most useful information and actions are easier to spot and use.

Expected result

A clearer and more useful header, with better visibility on key information, faster access to common filters, and a more intuitive way to create a new intent.
