fix(novelarrow): Moved Novel Arrow to Novel Ping with readnovelfull multisrc

[D3ICIDE]

Checklist

Closes: #2572

#2574 creates its own implementation of readNovelFull instead of using the multisrc.
#2618 I don't even think this works atleast according to my testings and the fact that the site doesn't even use that structure anymore.
Kept Novel Bin and Novel Arrow so that users could read already downloaded chapters

• Test changes in Plugin Playground or the app

Summary

This PR adds Novel Ping to the shared ReadNovelFull reader, with listing and genre filters. It also updates shared cover and chapter-link parsing and removes the reader’s conditional image Referer setup.

• Novel Ping appears as a source in the shared novel reader.
• Novel Ping listings offer three sorting choices.
• Novel Ping readers can browse novels by genre.
• Novel covers use the image fields each page provides.
• AJAX chapter links become paths the reader can open.
• The shared reader no longer adds a site Referer to image requests.
