Generate BCS schemas for emitted event structs

[avbel]

Summary

• Emit export const <Event> = bcs.struct(...) for every emitted event (with --events), alongside the existing parsedJson string export type, so callers can decode raw event BCS bytes (SuiEvent.bcs) into typed values.
• Field keys use the same camelCase convention as param-struct BCS schemas (reuses the existing to_bcs_struct_schema helper). The schema const coexists with the snake_case export type (TS keeps type and value namespaces separate, so sharing the event name is legal).
• Extended bcs/Address import detection so event-only modules still import what they need.

Test plan

• cargo fmt && cargo clippy --all-targets -- -D warnings && cargo test — green (136 unit + 7 integration)
• New unit tests: camelCase BCS schema emission, event-only bcs import, no schema when --events disabled, single schema const when event is also a param (no name clash)
• Extended full_pipeline_events integration assertions for exact export const ... bcs.struct(...) output
• generated_ts_compiles_with_tsc run for real against @mysten/sui v2.9 — generated event BCS schemas typecheck

Pull request overview

This PR extends the TypeScript generator to emit BCS schema constants for Move structs that are detected as emitted events (when --events is enabled), enabling callers to decode raw SuiEvent.bcs bytes into typed values using bcs.struct(...).

Changes:

• Generate export const <EventName> = bcs.struct(...) for each emitted event struct, using camelCase field keys (via the existing to_bcs_struct_schema helper).
• Extend bcs / bcs.Address import detection so event schemas trigger the correct @mysten/* import even when events are the only reason BCS is needed.
• Add/extend unit + integration test assertions for schema emission, naming/collision behavior, and import selection; update pinned Sui Move compiler git rev.
