fix(MangaDemon): fix blurred search/home page thumbnail by hardcoding content rating

[mjishnu]

Summary

both home page and search page showed blurred thumbnail due to content rating not being set, paperback by default blurs unrated content. the homepage/search page doesn't have any flag to use for custom content rating so switch to hardcoded "safe" value since managdemon is not a mature.

Why not set the content rating only at where it returns the results to the app, setting content rating multiple places and changing the model seems a bit excessive

refactored as per your suggestion.

huh I didn't overwrite though? the force push is actually commit rename i did since there was a typo in it.

I just moved the loops and content rating to a common function into main.ts (no parser.ts clutter) wasn't this your recommendation though? the current code content ratting is set in like 6 places and the same loop is duplicated in multiple places isn't just placing them in a common function better or are there any specific reason you did code duplication?

  private registerItems<T extends { mangaId?: string; contentRating?: ContentRating }>(
    items: T[],
  ): T[] {
    for (const item of items) {
      if (item?.mangaId) {
        this.idMap[item.mangaId.replace(/[^a-zA-Z0-9]/g, "")] = item.mangaId;
      }
      if (item) item.contentRating = ContentRating.EVERYONE;
    }
    return items;
  }

btw i am new to this extension development i just did this since mangademon is a source i use and the blur was annoying i am fine with any approach as long as the issue is resolved
