Alex Cheema eb9228615f models: add MiniMax M2.7 cards (#1884) ...

## Motivation

The mlx-community [MiniMax-M2.7
collection](https://huggingface.co/collections/mlx-community/minimax-m27)
landed but exo didn't have model cards for any of the variants yet, so
they weren't selectable from the dashboard model picker. Adding cards
also makes them discoverable under the existing MiniMax family entry.

## Changes

Added 6 new model cards in `resources/inference_model_cards/`, one per
quant of MiniMax M2.7:

- `mlx-community--MiniMax-M2.7.toml` (bf16, full precision — 457 GB)
- `mlx-community--MiniMax-M2.7-4bit.toml` (128 GB)
- `mlx-community--MiniMax-M2.7-4bit-mxfp4.toml` (121 GB)
- `mlx-community--MiniMax-M2.7-5bit.toml` (157 GB)
- `mlx-community--MiniMax-M2.7-6bit.toml` (185 GB)
- `mlx-community--MiniMax-M2.7-8bit.toml` (243 GB)

All six use `family = "minimax"` and share `base_model = "MiniMax M2.7"`
so they collapse into a single group in the picker with the existing
MiniMax logo. Architecture fields (`n_layers = 62`, `hidden_size =
3072`, `num_key_value_heads = 8`, `context_length = 196608`) were read
from each repo's `config.json`; `storage_size.in_bytes` was summed from
the HF tree API per repo.

`capabilities = ["text", "thinking"]` follows the existing MiniMax M2.5
cards — the chat template always emits `<think>` tags (no toggle),
matching M2.5 behavior.

## Why It Works

Model cards in `resources/inference_model_cards/` are auto-loaded by
`src/exo/shared/models/model_cards.py::get_model_cards`. The dashboard
picker groups by `base_model` and filters by `family`, so sharing both
across all six variants gives a single "MiniMax M2.7" group under the
MiniMax sidebar entry, with the quant variants exposed as selectable
sub-options.

## Test Plan

### Manual Testing
<!-- Hardware: MacBook Pro M3 Max -->
- Ran `uv run python -c "…await get_model_cards()…"` and confirmed all 6
new cards load with `family=minimax`, `base_model="MiniMax M2.7"`, and
correct quant + byte sizes.
- `cd dashboard && npm run build` then `uv run exo`, opened the model
picker → **MiniMax** family → **MiniMax M2.7** group shows all six quant
variants.

### Automated Testing
- No new automated tests — these are data files validated by the
existing Pydantic `ModelCard` schema at load time.
