Add [CHANNEL+1] placeholder support for Hikvision-style channel numbering

- Added [CHANNEL+1], [channel+1], {CHANNEL+1}, {channel+1} placeholders to builder.go
- Updated 14 camera brands with universal channel patterns
- Hikvision: replaced 10 hardcoded patterns with 6 universal patterns
- Hiwatch: replaced 4 hardcoded patterns with 8 universal patterns (including ISAPI)
- Other brands: Annke, Swann, Abus, 7links, LevelOne, AlienDVR, Oswoo, AV102IP-40, Acvil, TBKVision, Deltaco, Night Owl
- Universal patterns placed first for faster discovery, hardcoded patterns kept as fallback
- Supports both 0-based (channel=0 -> 101) and 1-based (channel=1 -> 101) numbering
- Added 6 high-priority patterns to popular_stream_patterns.json
