Subject: [PATCH] fix: improve quality detection regex to match 2160p, UHD,
 FullHD and other keywords (#450)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## What

Two-line fix to the quality detection regex in
`media_manager/indexer/schemas.py`.

**UHD pattern**: `\b(4k)\b` → `\b(4k|2160p|uhd)\b`
**FullHD pattern**: `\b(1080p)\b` → `\b(1080p|fullhd|full\s*hd)\b`

## Why

The UHD regex only matched the literal keyword `4k`. Torrent titles
containing `2160p` or `UHD` (but not `4k`) were classified as
`Quality.unknown` (value 5) instead of `Quality.uhd` (value 1). Since
sorting uses quality as the primary key, these 4K releases ended up at
the bottom of search results.

### Example

| Title | Before | After |
|---|---|---|
| `Movie.2013.4K.HDR.2160p.x265` | ✅ `Quality.uhd` | ✅ `Quality.uhd` |
| `Movie.2013.UHD.BluRay.2160p.HDR10.x265` | ❌ `Quality.unknown` | ✅
`Quality.uhd` |
| `Movie.2013.2160p.WEBRip.DDP5.1.x264` | ❌ `Quality.unknown` | ✅
`Quality.uhd` |

All patterns already use `re.IGNORECASE`, so case variants are handled.

Fixes #449
