feat: Add audio to meditations 🎧 #14

Overview

Enhance the meditation functionality by adding audio playback support. Meditations are currently displayed as cards grouped by categories, with their data stored directly in the code (e.g., as a local array or object). This enhancement will allow users to listen to guided audio for each meditation.

• Meditation Model and UI: Located in src/pages/Meditations.tsx.

Update:
src/meditations, we want to have the audio tab now functioning. We are focusing on the meditation section of the audio tab using the uploaded meditations. Link the mp3 files to the meditations so the playback, start, end and pause buttons all work holistically. For any cards not used, have a blurred coming soon sign on them.
