Add BUBBLE protocol support for XMeye/HiSilicon NVR/DVR cameras

Implemented comprehensive BUBBLE protocol support for Chinese NVR/DVR cameras (ZOSI, SANNCE, ANNKE, FLOUREON, XMeye). This proprietary protocol requires HTTP with embedded credentials and special handling.

Changes:
- Added BUBBLE entries to brand databases with main/sub stream support
- Extended URL placeholder system to support {channel} syntax
- Implemented BUBBLE-specific stream generation with credential embedding
- Added BUBBLE stream detection via Content-Type: video/bubble
- Updated Frigate/Go2RTC generators to convert BUBBLE URLs to bubble:// format
- Added BUBBLE patterns to popular stream database

Technical details:
- BUBBLE uses HTTP protocol with credentials in URL (bubble://user:pass@host:port/path)
- Supports dual streams: stream=0 (main) and stream=1 (sub)
- Requires video=copy parameter for optimal performance in go2rtc
- Detection prioritized before generic HTTP checks to ensure correct identification
