fix(ru.desu): improve Ranobe chapter and catalog support

[kurisumakis3]

Summary

• Switch Ranobe chapter listing to the JSON API and keep legacy URL chapter keys/deep links resolvable.
• Preserve existing details on chapter-only refreshes; surface deep-link errors and clarify chapter-access 401s.
• Parse typed text/image blocks, retain text block boundaries/line breaks/basic emphasis, and keep image-only chapters as image pages.
• Add confirmed Ranobe metadata and public status/genre filters; update docs and source version to 7.

Validation

• cargo fmt --check
• cargo test --target wasm32-unknown-unknown (25 tests)
• cargo clippy --target wasm32-unknown-unknown -- -D warnings
• cargo check --target wasm32-unknown-unknown
• aidoku package, aidoku verify, and unzip -t
• Manual device check: the packaged v7 candidate was reported to work; this was informal, not an exhaustive matrix.

can you run cargo update to update the aidoku-rs dependency?

[kkantan]

the query should never be empty, so this check isn't necessary. you're also unwrapping and rewrapping the query. you could simply check if query.is_some() then qs.push("search", query).

Updated in 3f2a918. cargo update -p aidoku advanced both aidoku and aidoku-test to ae6485e3; only their shared git revision changed in Cargo.lock. I simplified optional query handling after confirming the Aidoku v0.9 bridge turns empty input into None. Local checks pass: fmt, 25 WASM tests, Clippy (-D warnings), check, package, verify, and archive integrity. GitHub Actions are running now.

Review follow-up

Applied in commit 3f2a918:

• Updated the shared aidoku-rs git revision for aidoku and aidoku-test in sources/ru.desu/Cargo.lock.
• Simplified Ranobe search query handling; the Aidoku v0.9 bridge maps empty query input to None.
• Left ContentRating as Unknown when the site provides only ordinary genre tags and no explicit safe rating.

Local verification passed: cargo fmt --check, 25 WASM tests, Clippy with -D warnings, cargo check, package, aidoku verify, and archive integrity. GitHub Actions for the new head are running; I will request review again after they finish.
