Fix Aisha NPC bubble text overlapping with pond and outdated content

### Build version
Not specified

### Issue Description
When clicking on Aisha NPC to start a conversation, the bubble text visually overlaps with the pond. Additionally, the text content is outdated and does not reflect the current activities available in the experience.

Two separate problems have been identified:
1. **Visual overlap** — the bubble text clips into/behind the pond due to the first camera waypoint position.
2. **Outdated content** — the NPC text does not reflect activities currently available (e.g. fishing pond, fire pit).

A fix is already in progress by @bvargasp: converting the UI from 3D planes to 2D UI elements (for better mobile readability) and adjusting the first camera waypoint to avoid clipping the pond.

### STR (Steps to Reproduce)
1. Open the app
2. Navigate to Aisha NPC
3. Click on Aisha to start a conversation

### Expected Result
Bubble text is fully visible without overlapping any environmental elements, and the content is up to date with currently available activities.

### Actual Result with evidence
The bubble text overlaps with the pond. The text content is also outdated and does not match available in-experience activities.

### Reproduction
Always (100%)

### Operative system and additional Notes
Windows

Start by reproducing the conversation at Aisha NPC and inspect the current 3D-plane conversation UI and first camera waypoint. Compare the displayed text with the currently available fishing pond and fire pit activities; done means the bubble remains fully visible and the content is current, including on mobile.
