The is_a frontmatter key was appearing both as the TypeRow badge and
as a regular editable property. Added both 'is_a' and 'Is A' variants
to SKIP_KEYS to prevent duplication (snake_case used in mock data,
space-separated used in real vault YAML).
Added test verifying is_a is skipped when TypeRow is present.

Split the Properties panel into two visually distinct sections:
1. **Properties** (editable): frontmatter properties with interactive
hover background, cursor pointer, and click-to-edit. Includes Type
row, Status, Owner, tags, and all user-defined properties.
2. **Info** (read-only): derived metadata shown below a border
separator with an "Info" header. Uses muted color (--text-muted)
with no hover states or click interaction. Includes:
- Modified date
- Created date (new)
- Word count
- File size (new, formatted as B/KB/MB)
Product decisions:
- Info section uses --text-muted for both labels and values (more
dimmed than the --muted-foreground used by editable labels)
- Editable rows get rounded hover:bg-muted on the full row
- Type row stays at top of Properties as an identity element
- Added Created date and file Size to give more useful metadata
