Add more preconfigured profiles for ZetaClient chaos mode

[lumtis]

Follow up of #4408

Investigate preconfigured profiles as in the PR for some targeted tests.

Example: high failure rate for inbound observation related functions for testing inbound performance but low or 0 value for the others. Same idea for outbound performance.

A summary of the changes CodeRabbit can apply:

• Add six preconfigured JSON chaos profiles (inbound-stress.json, outbound-stress.json, tss-stress.json, network-instability.json, rpc-instability.json, zetacore-stress.json) to zetaclient/mode/chaos/profiles and three documentation files (profiles/README.md, profiles/CHANGELOG.md, PROFILES.md) to provide targeted, reproducible failure-testing configurations with usage examples.

• Add a new chaos mode profiles package by creating zetaclient/mode/chaos/PROFILES.md, zetaclient/mode/chaos/profiles/README.md and CHANGELOG.md, and six JSON profile files (inbound-stress.json, outbound-stress.json, tss-stress.json, network-instability.json, rpc-instability.json, zetacore-stress.json) to provide ready-to-use failure-percentage configurations and documentation for chaos testing (linked to PR test: add chaos mode capabilities to zetaclient localnet #4408).
