fix(tui): log image debug

[resolvicomai]

What?

• route image protocol debug messages through the standard logger instead of writing directly to stdout
• add coverage that verifies debug output goes to the logger and leaves stdout untouched

Why?

Debug output should respect the application logging path instead of bypassing logger formatting and destinations.

Fixes #701

Tests

• go test ./view -count=1
• make lint
• go test ./...

Hi @resolvicomai! Please fix the following issues with your PR:

• Title: Is too long (41 characters). The PR title must be strictly under 40 characters.
• Body: Missing the ## What? or ## Why? headings required by the PR template.

Formatting issues have been resolved. Thank you!

@resolvicomai we are migrating to a new log introduced in #1311. Please use loglevels internal package

[resolvicomai]

Thanks. I pushed a follow-up that uses the internal loglevel package for the image protocol debug log and simplifies the test so it only asserts logger output.

Validation:

• go test ./view
• go test ./...
• make lint
• git diff --check
