Bandwidth selector highest bandwidth does not account for transcoding to less efficient codec

[felix920506]

Describe The Bug
The bandwidth selector has the highest option capped at the source file bandwidth. However, when transcoding to a less efficient (eg. HEVC -> H264), the highest bandwidth shown is lower than what auto would set it to under ideal network conditions

Steps To Reproduce

1. Start a video playback
2. Open the bandwidth selector
3. See error

Expected Behavior
There should be options that are a good amount higher than the source bandwidth

System (please complete the following information):

• Platform: all
• Browser: all
• Jellyfin Version: 10.10.3

Additional Context
On a video I have, the source bitrate is 2mbps. On auto select with ideal network conditions, transcoding to H264 will have auto set bandwidth of 6.7mbps. However, the selector only has up to 3mbps to choose.

Lines 41 to 45 in 235aced

	// Slightly increase reference bitrate for high efficiency codecs when it is not too high
	// Ideally we only need to do this for transcoding to h264, but we need extra api request to get that info which is not ideal for this
	if (videoCodec && ['hevc', 'av1', 'vp9'].includes(videoCodec) && referenceBitRate <= 20000000) {
	referenceBitRate *= 1.5;
	}

I think one way would be to always show options below 10mbps regardless of source bitrate?
