/**
 * Replaces `{{key}}` handlebars in a template string with matching property values from `item`.
 *
 * Originally handled only two replacements. Refactored to support any number of handlebars,
 * specifically to support Drilldown `linkSubstitute` where multiple field values are substituted
 * into a single URL string (e.g. to pre-fill a SharePoint form via query parameters).
 *
 * Key normalization: each `{{key}}` is trimmed and any `/` characters are removed before
 * looking up the value on `item`. This is consistent with how Drilldown handles lookup columns
 * (e.g. `{{AssignedTo/Title}}` becomes `AssignedToTitle`).
 *
 * NOTE: A similar general-purpose function exists at src/logic/Strings/handleBarsHTML.tsx
 * (`replaceHTMLHandleBars`) — consider that for non-URL use cases.
 *
 * @param item            - The list item object whose properties fill the handlebars.
 *                          Values are coerced to string via String(). Null/undefined are treated as missing.
 *
 * @param handleBarString - The template string containing one or more `{{key}}` placeholders.
 *                          Example: `"https://example.com?Title={{Title}}&Category={{Category}}"`
 *
 * @param emptyIfSubEmpty - Legacy parameter. When true and any substitution value is missing,
 *                          the entire result is returned as `''`.
 *                          Equivalent to passing `emptyHandling = 'omitAll'`.
 *                          Ignored when `emptyHandling` is set.
 *
 * @param maxReplacements - Optional. Limits how many handlebars are substituted, left to right.
 *                          Any handlebars beyond the limit are left intact as `{{key}}`.
 *                          Omit or pass undefined to replace all handlebars.
 *
 * @param emptyHandling   - Optional. Controls what happens when a value is missing/null/undefined.
 *                          Each slot is handled independently — only the missing ones are affected.
 *
 *   'omitAll'  - If ANY value is missing, return `''` for the whole string.
 *                Explicit equivalent of `emptyIfSubEmpty = true`.
 *
 *   'empty'    - Substitute missing values with `''`, leaving the placeholder param in the result.
 *                Example: `&Category=` (empty value, param stays).
 *                Safe for use with URLs and plain text strings.
 *
 *   'omit'     - Substitute missing values with `''`, then strip those entire query parameters
 *                from the URL result. Intended for URL strings only.
 *                Example: `&Category=` is removed entirely.
 *                Only slots with missing values are removed — all others remain intact.
 *
 *   'preserve' - Leave the original `{{key}}` handlebars unchanged for any missing values.
 *                Useful when the template may be re-processed later, or when you want
 *                to return the original string unchanged for unmatched fields.
 *
 *   default    - When no `emptyHandling` is set and `emptyIfSubEmpty` is false,
 *                behaves the same as 'preserve': missing values keep their `{{key}}` intact.
 *
 * @returns The substituted string, or `''` if `emptyIfSubEmpty`/`'omitAll'` is triggered.
 *          Returns `handleBarString` unchanged if it is not a string type.
