feat: bump tonic 0.12→0.14 + tonic-web-wasm-client 0.6→0.9 + prost 0.13→0.14

[satyakwok]

Cluster A3 of the major-bump audit (explorer V2 side — completes Cluster A).

Changes

• runtime: tonic 0.12 → 0.14, tonic-web-wasm-client 0.6 → 0.9, prost 0.13 → 0.14
• build-deps: tonic-build → tonic-prost-build (0.14), prost-build 0.13 → 0.14
• new dep: tonic-prost 0.14 (runtime)

API migrations

• tonic_build::configure() → tonic_prost_build::configure()
• .compile_protos_with_config() → .compile_with_config() (renamed in 0.14)
• tonic feature prost removed (provided by separate tonic-prost crate)

Verification

• cargo check --target wasm32-unknown-unknown — clean (browser bundle)
• cargo check --features ssr — clean (axum server build)

Both code paths the explorer ships (CSR/hydrate in browser, SSR axum binary on the host) compile.

Supersedes #15, #23. Coordinates with sdk-rs#15 and sentrix-grpc-wasm#12 (both already opened in this cluster).

Summary by CodeRabbit

• Chores
  • Updated gRPC-Web and protocol buffer dependencies (tonic, prost, tonic-prost, tonic-web-wasm-client) and WASM networking dependency for improved compatibility and stability.
  • Updated build-time code generation tooling to align with the new dependency versions and maintain proto code generation behavior.

📝 Walkthrough

Walkthrough

This PR upgrades the gRPC-Web and protocol buffer code generation stack across build and runtime dependencies. The build system migrates from tonic-build to tonic-prost-build 0.14 with prost-build 0.14, updating build.rs to use the new prost-focused API while preserving client generation and conditional server stub generation. Runtime dependencies for gRPC-Web clients are coordinated: tonic advances to 0.14 with feature set narrowed to ["codegen"], tonic-web-wasm-client moves to 0.9, and prost moves to 0.14.

Title check	✅ Passed	The title clearly summarizes the main change: a coordinated dependency upgrade of tonic, tonic-web-wasm-client, and prost versions.
Description check	✅ Passed	The PR description includes a clear summary of changes, API migrations applied, and verification steps. However, it does not follow the template structure (missing formal Test plan section with checklist) though content covers verification.
