feat: Fix modeline lag and add org multi-level sort with comprehensive tests

Performance improvement and new feature with full test coverage.

## Changes

### 1. Fix modeline line/column position lag (#A priority)
- Replace expensive line-number-at-pos with cached %l/%c format specifiers
- Enable line-number-mode explicitly for caching
- Result: Instant modeline updates, zero performance overhead
- Files: modules/modeline-config.el:81-83, modules/ui-config.el:53

### 2. Implement multi-level org sorting
- New function: cj/org-sort-by-todo-and-priority
- Sorts by TODO status (TODO before DONE) AND priority (A→B→C→D)
- Uses stable sorting: priority first, then TODO state
- Gracefully handles empty sections (no error)
- Bound to C-; o o (ordering → org sort)
- Files: modules/org-config.el:278-299, modules/custom-ordering.el:253,267

### 3. Comprehensive ERT test suite (12/12 passing)
- Normal cases: Mixed TODO/DONE, multiple of same type, same priority
- Boundary cases: Empty sections, single entries, no priorities
- Error cases: Non-org-mode buffer
- Test file: tests/test-org-sort-by-todo-and-priority.el

### 4. Testing improvements discovered
- Disable org-mode hooks to avoid package dependencies in batch mode
- org-sort-entries must be called from parent heading
- Preserve priority cookie in org-get-heading (t t nil t)
- Add condition-case to handle "Nothing to sort" gracefully

### 5. Minor cleanup
- Comment out chime-debug setting (org-agenda-config.el:267)
- Mark modeline lag task as DONE in todo.org

## Technical Details

Modeline optimization:
- line-number-at-pos is O(n) where n = current line
- %l and %c are O(1) lookups from cached values

Org sorting algorithm uses stable sort:
1. Sort by priority (A, B, C, D, unprioritized)
2. Sort by TODO status (preserves priority order within groups)
Result: TODO [#A], TODO [#B], DONE [#A], DONE [#B], etc.

+
+** TODO [#A] Fix Google Calendar password prompts every 15 minutes
+
+IRRITANT: gcal-sync triggers password prompts approximately every 15 minutes,
+interrupting workflow and breaking focus. This defeats the purpose of having
+passphrase caching configured.
+
+**Current Setup:**
+- GPG agent configured with 400-day cache (gpg-agent.conf):
+  - default-cache-ttl 34560000
+  - max-cache-ttl 34560000
+  - allow-loopback-pinentry enabled
+- Plstore caching enabled (auth-config.el:54):
+  - plstore-cache-passphrase-for-symmetric-encryption t
+  - plstore-encrypt-to nil (symmetric encryption)
+- Auth-source cache: 24 hours (auth-config.el:31)
+- Auto-sync interval: 30 minutes (org-gcal-config.el:50)
+
+**Problem:**
+Despite proper GPG agent caching, oauth2-auto.plist prompts for passphrase
+every ~15 minutes during gcal-sync operations. This suggests:
+1. plstore may not be using GPG agent cache properly for symmetric encryption
+2. oauth2-auto token refresh might be bypassing cache
+3. EPinentry mode may need explicit configuration (currently commented out)
+
+**Goal:**
+Passphrase should be entered ONCE per Emacs session, then cached until Emacs
+closes. No interruptions during normal work.
+
+**Investigation Paths:**
+1. Check if oauth2-auto respects plstore passphrase caching
+2. Investigate plstore symmetric encryption cache behavior with GPG agent
+3. Test enabling epa-pinentry-mode 'loopback (auth-config.el:42)
+4. Check oauth2-auto token refresh cycle vs password prompt timing
+5. Consider oauth2-auto configuration options for token persistence
+6. Review org-gcal or oauth2-auto issues for similar problems
+
+**Files:**
+- modules/auth-config.el (plstore and GPG configuration)
+- modules/org-gcal-config.el (org-gcal and oauth2-auto setup)
+- ~/.gnupg/gpg-agent.conf (GPG agent cache settings)
+- oauth2-auto.plist (encrypted OAuth tokens - prompts every access?)

-✅ Fixed keybinding issue in org-mode buffers.
+✅ Fixed modeline position lag by replacing expensive function calls with cached values.
 
 **Problem:**
-1. Autoload cookies were just comments and never executed
-2. Org-mode was overriding C-' with org-cycle-agenda-files
+- Line/column numbers lagged behind cursor movement
+- Used `line-number-at-pos` which counts from buffer start on every update
+- Performance degraded in large files
 
 **Solution:**
-- Set keybindings directly when module loads (lines 239-240)
-- Explicitly override org-mode's C-' after org loads (lines 244-245)
-- Both C-' and C-c f now work correctly in all buffers including org-mode
+- Replaced with built-in format specifiers `%l` and `%c` (modeline-config.el:81)
+- These use cached values maintained by line-number-mode and column-number-mode
+- Explicitly enabled line-number-mode in ui-config.el:53
+- Zero performance overhead - cached values update instantly
 
-File modified: modules/flyspell-and-abbrev.el:235-251
