Fix "ScriptProperties is not defined" (and UiApp, DocsList, ScriptDb…)

ReferenceError: ScriptProperties is not defined
TypeError: Utilities.jsonParse is not a function
ReferenceError: UiApp is not defined

Projects old enough to run on Rhino usually also call services Google has since shut down. Migrating to V8 is the moment to fix them.

Direct replacements

Removed	Use instead
`ScriptProperties.getProperty(k)`	`PropertiesService.getScriptProperties().getProperty(k)`
`UserProperties.setProperty(k, v)`	`PropertiesService.getUserProperties().setProperty(k, v)`
`DocumentProperties.…`	`PropertiesService.getDocumentProperties().…`
`Utilities.jsonParse(s)` / `jsonStringify(o)`	`JSON.parse(s)` / `JSON.stringify(o)`
`Session.getTimeZone()`	`Session.getScriptTimeZone()`
`Session.getUser()`	`Session.getActiveUser()` / `Session.getEffectiveUser()`

// Old
ScriptProperties.setProperty('lastRun', new Date().toISOString());
var cfg = Utilities.jsonParse(UserProperties.getProperty('cfg'));

// Current
PropertiesService.getScriptProperties().setProperty('lastRun', new Date().toISOString());
var cfg = JSON.parse(PropertiesService.getUserProperties().getProperty('cfg'));

Services that need a rewrite

UiApp → HtmlService (sidebars/dialogs) or CardService (add-ons).
DocsList → DriveApp (getFilesByName, getFolderById, searchFiles).
ScriptDb → a Sheet, PropertiesService for small data, or JDBC / Firestore.
Xml (old service) → XmlService. SoapService → UrlFetchApp + XmlService.
ContactsApp (deprecated) → People advanced service.

How V8Shift handles it

Properties, Utilities.json* and the deprecated Session methods are rewritten automatically. UiApp, DocsList, ScriptDb, Xml, SoapService and Finance are flagged for manual work.
