Subject: [PATCH] fix: align message trimming with configured maxLength
 (#13947)

# Pull Request Template

## Description

This PR fixes
1. Messages being trimmed to the default 1024 limit in `trimContent`
method, instead of channel-specific limits for drafts and AI tasks.
2. Telegram messages are allowed up to 10,000 characters in config, but
the API supports only 4096, causing failures for oversized messages.
