Fix calendar: MySQL 8.0 anniversary query crash and Quill toolbar duplication (#8128)

- [x] Fix MySQL 8.0 DATE filtering in AnniversariesCalendar.php
- [x] Fix Quill editor toolbar duplication (mount-once useEffect +
onChangeRef)
- [x] Add Cypress regression tests
- [x] Fix CI failure: replace `eslint-disable-next-line` with
`biome-ignore` comment in QuillEditor.tsx
- [x] Add `value` sync effect using `clipboard.convert` + `setContents`
(proper Quill API, preserves undo history vs raw innerHTML)
- [x] Improve Cypress test: wait for at least one toolbar before
asserting exact count of 2

> <issue_description>Hello @DawoudIO ,
> 
> ## Quick, friendly bug report
> 
> Thanks for helping us improve ChurchCRM. Clear details help us triage
and fix bugs faster.
> 
> Please share:
> - **What happened**:  
> I was in the process of manual installation of ChurchCRM 7.0.0 on Alma
Linux 8.10 with PHP 8.4, MYSQL 8.0, Apache 2.4 using
https://github.com/ChurchCRM/CRM/releases/download/7.0.0/ChurchCRM-7.0.0.zip.
> 
> However, when I visit Calendar-> Select a specific date by clicking on
it -> Enter event title or select any option from dropdown i.e event
type or pinned calendars the toolbox keeps up adding another toolboxes
and this slows down the browser.
> 
> Also cannot enter any description in Description field or text in
'Text' field or save any event.
> 
> - **Steps to reproduce**:
> - Install Churchcrm
> - Go to Calendar -> Click on Specific date -> Try to add event title
or select anything from dropdowns .
> - Toolbox(Editors) keep on expanding and slow down the browser
> 
> - **What you expected**: What should have happened instead
> - Churchcrm event calendar should have worked properly.
> 
> If you're an admin and can access the app, the fastest way to collect
debug info:

> **Admin → System Maintenance → System Logs** (or click the debug
icon). Attach logs/screenshots if available — please redact private
data.

+**CRITICAL:** MySQL 8.0+ strict mode rejects comparing DATE columns to empty strings (`''`), returning `SQLSTATE[HY000]: 1525 Incorrect DATE value: ''`.

+->filterByWeddingdate(null, Criteria::ISNOTNULL)
+// Generates: WHERE wedding_date IS NOT NULL → Works on all MySQL versions
+```
+
+**Why this matters:** Empty string literals are invalid for DATE type in strict mode. Use `ISNOTNULL` criteria when filtering for non-empty dates; use `null` value with `ISNOTNULL` criterion (not an empty string).

+## Biome Lint — Suppression Comments <!-- learned: 2026-03-03 -->
+
+This project uses **Biome** (not ESLint) for TypeScript/React linting. ESLint suppression comments are silently ignored by Biome.
+
+### ❌ WRONG — ESLint comment does nothing in this repo
+```ts
+// eslint-disable-next-line react-hooks/exhaustive-deps
+useEffect(() => { ... }, []);
+```
+
+### ✅ CORRECT — Biome suppression syntax
+```ts
+// biome-ignore lint/correctness/useExhaustiveDependencies: <reason>
+useEffect(() => { ... }, []);
+```
+
+### Common rules to suppress
+
+| Rule | When |
+|------|------|
+| `lint/correctness/useExhaustiveDependencies` | `useEffect` / `useCallback` with intentional empty or partial deps |
+| `lint/suspicious/noExplicitAny` | Legitimate `any` in interop/legacy code |
+| `lint/style/noNonNullAssertion` | When null is structurally impossible |
+
+### React `useEffect` mount-once pattern (Quill, charts, D3, etc.)
+
+When initializing a third-party DOM library that must only run once:
+
+```ts
+// Keep a ref to the latest callback so the handler never goes stale
+const onChangeRef = useRef(onChange);
+useEffect(() => {
+  onChangeRef.current = onChange;
+}, [onChange]);
+
+// biome-ignore lint/correctness/useExhaustiveDependencies: initialized once on mount; re-running would create duplicate DOM nodes. name/placeholder are mount-time constants; onChange uses onChangeRef; value is synced by a separate effect.
+useEffect(() => {
+  // ... initialize library ...
+}, []);
+
+// Sync controlled value changes without re-initializing
+useEffect(() => {
+  if (instanceRef.current) {
+    instanceRef.current.root.innerHTML = value ?? "";
+  }
+}, [value]);
+```
+
+**Why `[]`?** Libraries like Quill append DOM nodes into a container. Re-running the effect without destroying the old instance first creates duplicate toolbars/canvases. The guard `if (instanceRef.current) return;` only partially mitigates this.
