Summary and experience bullet fields in the review modal are now
editable textareas. Edited values flow through decisions to
apply_review_decisions(), which uses edited_text/edited_bullets when
the section is accepted. Clearing unwanted LLM-added bullets (empty
lines filtered server-side) addresses the extra-bullets issue.
The preview textarea in the apply workspace is also now editable;
approveResume() passes preview_text_override so manual edits survive
the approve step without re-rendering from struct.
