models: name GPT-5.6, Grok 4.5 and ClinePass slugs instead of showing raw ids

Several model ids price correctly but had no SHORT_NAMES entry, so the
By Model panel rendered the raw slug next to properly named siblings:
`gpt-5.6-sol`, `gpt-5.6-terra`, `gpt-5.6-luna`, `grok-4.5`,
`qwen3.7-max`, `minimax-m3` and `mimo-v2.5-pro`.

All display-only; no dollar amounts move.

Notes on the less obvious ones:

- The GPT-5.6 variants are listed individually rather than as a bare
  `gpt-5.6`. A base entry would swallow every future `gpt-5.6-*` through
  the prefix match and hide the variant behind a sibling's label, which
  is exactly what getShortModelName's version-boundary rule prevents. An
  unlisted variant still falls through to its raw id, and there is a test
  pinning that.
- `grok-4.5` is the model the Grok Build harness runs and reports as
  `current_model_id`, so it takes the model's own name. Ids that really
  are `grok-build*` keep the "Grok Build" label, also covered by a test.
- ClinePass routes models as `cline-pass/<slug>`. No new prefix handling
  was needed: getShortModelName's path fallback already strips the
  prefix and re-resolves the bare slug, the same way it handles
  `accounts/fireworks/models/<slug>`.
- MiniMax M3 is mapped under both the lowercase OpenRouter slug and the
  capitalized spelling sessions report, since SHORT_NAMES matching is
  case-sensitive (the case-insensitive index covers pricing only).

`mimo-v2.5-pro` remains unpriced upstream; this only gives it a name.
