/**
 * Derive a human-readable display name for a serving endpoint.
 *
 * When `provided` is a non-blank string (a Databricks display-name tag or
 * external-model name), it wins verbatim (trimmed). Otherwise the endpoint
 * `name` is humanized: leading vendor prefixes (`databricks`, the
 * `system.ai` namespace, `dbx`) are dropped, then each `-`/`_`/`.`-separated
 * segment is title-cased (acronyms like GPT/GTE/BGE uppercased, "AI" kept),
 * runs of purely-numeric segments are joined into a dotted version
 * (`...-4-6` -> "4.6"), and a size unit glued to its number (`120b` ->
 * "120B"). Falls back to the trimmed raw `name` if stripping leaves nothing.
 *
 * @example
 * toModelDisplayName("databricks-claude-sonnet-4-6") // "Claude Sonnet 4.6"
 * toModelDisplayName("databricks-gpt-oss-120b")      // "GPT OSS 120B"
 * toModelDisplayName("system.ai.bge_large_en")       // "BGE Large En"
 * toModelDisplayName("x", "Claude 4.6 (Preview)")    // provided wins
