v1.3.0+138 Chanawoo

Chanawoo v1.3.0+138

Fixes awoo.cf downloads and the offline/saved section (#2, #3).

Fixes

• Can't download from awoo.cf — saving an awoo attachment failed with FilenameProblem: Supplied filename has no file extension. Meguca stores filenames without an extension (it derives it from the file type), so the app now rebuilds the proper name.ext before saving.
• Downloaded / saved-offline section wonky for awoo — downloaded awoo threads weren't serving their images offline because the media host wasn't recognized. awoo media now resolves correctly from local downloads.
• Hardened the native file-save path so a missing extension can no longer crash.

Also in this release line

• awoo.cf default site below 4chan + top of add-site picker (+137)
• owo.vg Gold Pass skips client post cooldown (+135)
• Upstream reply button fixes (+136)
