Explicit cloudflareClient if Cloudflare hosted

[vetleledaal]

Inspired by #6609, change necessitated by J2K not setting client to network.cloudflareClient.

Many moving pieces:

• All extensions using super.client explicitly were checked
• If baseUrl was hosted on Cloudflare it was changed
• 180/187† were multisrc and version was not bumped for these (for this code change)
• If the multisrc did not have client set‡ to network.cloudflareClient it was set and bumped
• This will bump 64 multisrc extensions and 6 individual extensions

† estimate
‡ blogtruyen, mangahub, mmrcms, pizzareader, zeistmanga

Yes, I am aware that changing super.client to network.cloudflareClient has no effect for multisrc extensions. The scope was limited to only target Cloudflare hosted services. Another angle may be revisited in another PR.

---

Has not been tested exhaustively since the code change itself is trivial. Relying on CI for lint issues. Reviewing this PR is probably difficult. Here are some notes I used, I'm not sure if it tells you (the reviewer) anything.

Themes modified and what client is set to (excluding mangahub because client was set in multisrc):

themePkg = 'blogtruyen'       unset
themePkg = 'fmreader'         cloudflare
themePkg = 'fuzzydoodle'      cloudflare
themePkg = 'gattsu'           cloudflare
themePkg = 'goda'             cloudflare
themePkg = 'heancms'          cloudflare
themePkg = 'keyoapp'          cloudflare
themePkg = 'liliana'          cloudflare
themePkg = 'madara'           cloudflare
themePkg = 'mangathemesia'    cloudflare
themePkg = 'manhwaz'          cloudflare
themePkg = 'mmrcms'           unset
themePkg = 'peachscan'        cloudflare
themePkg = 'pizzareader'      unset
themePkg = 'terrascan'        cloudflare
themePkg = 'wpcomics'         cloudflare
themePkg = 'zeistmanga'       unset
themePkg = 'zmanga'           cloudflare

Cloudflare sites were checked with:

rg --no-filename -C9999 "client(: OkHttpClient)? = super\.client" | grep -Eo 'https://[^"/]+' | grep -vF '$' | sort -u | xargs -I {} sh -c 'curl -sI --connect-timeout 10 --max-time 10 "{}" | grep -i "server:" | grep -qi "cloudflare" && echo "{}"'

Checklist:

• Updated extVersionCode value in build.gradle for individual extensions
• Updated overrideVersionCode or baseVersionCode as needed for all multisrc extensions
• Referenced all related issues in the PR body (e.g. "Closes #xyz")
• Added the isNsfw = true flag in build.gradle when appropriate
• Have not changed source names
• Have explicitly kept the id if a source's name or language were changed
• Have tested the modifications by compiling and running the extension through Android Studio
• Have removed web_hi_res_512.png when adding a new extension

most multisrc source here already use cloduflareclient in the multisrc so I don't think it should be changed here

[vetleledaal]

I have conditionally reverted the changes done in ./src/ for multisrc extensions. The overall diff should be smaller.

rg 'overrideVersionCode =' | cut -d: -f1 | cut -d/ -f1-3 | xargs git restore --source=HEAD~

How about cases where extensions are using network.client directly, which is same as super.client I think?

[vetleledaal]

Use of network.client would use the non-cloudflareClient in J2K. Since it is less commonly used than super.client I simply forgot about that usage pattern.
