Scheduling improvements (#3564)
* Handle case where initial API call fails * Error if scheduling fails to retrieve * Visual improvements for scheduling graph: - Fixes for vertical scales - Add "minimum stock level" line * Refactor / improve query for list of BOM items a part can exist in * Remove stock column from "substitute part" dialog - Stock quantity no longer available in this serailizer * Add a button to reload part scheduling information * Add extra information to part scheduling API - Include "speculative" quantity drawdown for build orders * Add table of scheduling data * Improved chart display - Adds "minimum" and "maximum" expected values - Adds table of scheduling information * Bump API version * Improve table rendering * Improve axis scaling * Add ability to dynamically refresh schedling data * JS linting * JS fix
