Use real DeepSeek V4 model IDs (deepseek-v4-pro / deepseek-v4-flash)

The previous release exposed `deepseek-v4` and `deepseek-v3` as the V4
model IDs in the dropdown, but those aren't accepted by the DeepSeek API
— calls returned 4xx and notes silently failed.

The actual API-accepted IDs are `deepseek-v4-pro` (1.6T/49B active,
flagship) and `deepseek-v4-flash` (284B/13B active, fast+cheap). Both
support a 1M context window and a 384K max-output cap. The legacy
`deepseek-chat` / `deepseek-reasoner` aliases stay in the list for
backward compatibility — DeepSeek deprecates them on 2026-07-24, after
which they continue to map to v4-flash (non-thinking and thinking).

_MODEL_MAX_COMPLETION updated from a placeholder 8K cap to the correct
384K cap so the chunk planner doesn't truncate long notes.
