rework the memory view and rename profiles to Agent

Replace the three separate memory editors with a card layout that shows the
source file, a plain-text summary, the last modified time, and the character
count for each section, so the stored files are visible without opening
them.

Rename the sidebar "用户" entry to "Agent" in both locales and add the
memory.editTitle, memory.writeTo, and memory.charCount strings.
