This is actualized version of this PR - https://github.com/louislam/uptime-kuma/pull/6192
But with tests and an additional change that allows to only store responses **for failed HTTP requests**.
Add response column to heartbeat table to store HTTP response data
* Add monitor configuration options: saveResponse (default: false), saveErrorResponse (default: false) and responseMaxLength (default: 10240 bytes)
* Response max length of 0 allows unlimited storage without truncation
* Response data accessible in notification templates via heartbeatJSON.response
* Add UI controls in monitor edit page with translations (EN)
* Only saves response data when explicitly enabled to minimize database impact
chore: Tests added
fix: Missing response field
