Subject: [PATCH] fix(model_prices): add minimax/MiniMax-M3 with correct
 max_input_tokens 1048576
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The MiniMax-M3 entry merged to main (via #29412) carries
max_input_tokens: 512000, which is MiniMax's long-context billing
threshold, not the model's input limit. M3 supports a 1M token
context window, consistent with the sibling MiniMax-M2.x entries.

This branch is based on litellm_oss_branch (per the contribution
flow), where the entry does not exist yet — so the corrected entry
is added; on sync with internal staging the conflicting 512000
value should be resolved to 1048576.
