fix: use safeRenderValue consistently for all content types

The isJsonObject branch was bypassing safeRenderValue and calling
JSON.stringify directly, which displayed raw JSON for structured
objects like { text, type } instead of extracting the text field.

Now all content goes through safeRenderValue which extracts .text
from content blocks and falls back to JSON.stringify only when
no text field is found.

Addresses review feedback from Greptile and Cursor bots.
