chore(events): bump to 1.6.0 to match on-chain upgrade

[0xdevcollins]

The testnet events contract was upgraded to 1.6.0 on 2026-07-28 (wasm hash bfc1710911afbf150cc6e48e9264e1def81cde954bad8ecbf42dc96954b11f5d, see deployments/testnet-upgrades.jsonl), but the source still declared 1.5.0. Bump events 1.5.0 -> 1.6.0 across INITIAL_VERSION, contractmeta, and the Cargo package version so source and chain agree.

Poem

A bunny bumps the version bright,
From five to six, a tidy flight.
The metadata hops in line,
Tests now thump their paws: “All fine!”
One carrot marks the new design.
