fix(obsidian): remove emojis from button labels

jQuery UI dialog buttons don't work properly with emojis in the label text.
Removed emojis from button labels while keeping them in the dialog content.

Changed:
- '🔍 Search' → 'Search'
- '📁 Browse' → 'Browse'

The emojis are still visible in the dialog content boxes, just not in the
actual button labels.
