build: use the Common NU7 dependency stack

[p0mvn]

Pins Zakura's Common dependencies to the immutable NU7 revision from zakura-core/common#474, replacing the remaining crates.io address, protocol, and transparent packages with their Zakura forks.

Zakura now uses the finalized NU7 branch ID 0x77190AD8 and converts Common's unconditional NU7 network-upgrade variant without an unstable cfg. The full workspace resolves one coherent Common type family.

Validation:

• cargo check --workspace --locked
• cargo fmt --all -- --check
• git diff --check

Stack dependency:

• This draft intentionally consumes unpublished 1.3.0-alpha.1 Common crates from the immutable fix(network): credit replenishment budget on failed dials #474 Git revision.
• The crates.io publish graph check will remain blocked until the Common stack is merged and those prerelease crates are published; this PR must not publish Zakura crates before then.

Additional validation:

• cargo test -p zakura-chain --locked
• cargo deny --workspace --all-features check bans licenses sources --allow banned
• cargo deny --workspace --all-features check advisories --allow banned
• cargo vet check --store-path ./qa/supply-chain/
• ./scripts/changelog.py check
