[claude-memory] Restore truncated main.tf — apply Phase 3 image flip on full file

The Phase 3 commit 3148d15d ran into a disk-full ENOSPC during edit
of stacks/claude-memory/main.tf, and the file was committed truncated
at line 286 mid-string ('Cor instead of 'Core Platform' / closing
braces). terraform validate failed with 'Unterminated template string'.
Restoring the trailing 2 lines + re-applying the
viktorbarzin/claude-memory-mcp:17 → forgejo.viktorbarzin.me/viktor/
claude-memory-mcp:17 cutover that Phase 3 was meant to do.
