Bumps the workspace sqlparser dependency from 0.45 to 0.61 and updates
the sole consumer (oximeter/db/src/sql/mod.rs) for the breaking API changes:

• ObjectName inner type changed from Vec<Ident> to Vec<ObjectNamePart>
• Ident gained a span field (use Ident::new() / Ident::with_quote())
• Expr::Value now wraps ValueWithSpan instead of Value
• Query.order_by changed from Vec<OrderByExpr> to Option<OrderBy>
• Query.limit/offset/limit_by consolidated into limit_clause
• OrderByExpr.asc/nulls_first moved into OrderByOptions
• New fields on Select, TableAlias, TableFactor, Join, Cte, With
• Bare JOIN now parses as JoinOperator::Join (distinct from Inner)
