Three changes to eliminate periodic LED stutters on high-LED-count
WLED devices:
1. DDP PUSH flag: re-enable on the last packet of each frame so WLED
waits for the complete frame before rendering (prevents tearing
from partial multi-packet frames).
2. Health check: skip HTTP probe while a target is actively streaming
to the device — the device is clearly online and the HTTP request
to the ESP causes LED output to stutter.
3. Brightness polling: cache the value after first fetch and reuse it
on subsequent 2-second UI refreshes instead of hitting the ESP
every cycle.

Baud rate is now a first-class device field, passed through the full
stack: Device model → API schemas → routes → ProcessorManager →
AdalightClient. The frontend shows a baud rate dropdown (115200–2M)
for Adalight devices in both Add Device and Settings modals, with a
live "Max FPS ≈ N" hint computed from LED count and baud rate.

Implements the second device provider (Adalight) for Arduino-based serial LED controllers,
validating the LEDDeviceProvider abstraction. Adds serial port auto-discovery, per-type
discovery caching with lazy-load, capability-driven UI (brightness control, manual LED count,
standby), and serial port combobox in both Add Device and General Settings modals.

Consolidate all device-type-specific logic into LEDDeviceProvider ABC
with provider registry. WLEDDeviceProvider handles client creation,
health checks, validation, mDNS discovery, and brightness control.
Routes now delegate to providers instead of using if/else type checks.
Add standby_required capability and expose device capabilities in API.
Target editor conditionally shows standby interval based on selected
device's capabilities.

Scan the local network for WLED devices advertising _wled._tcp.local.
and present them in the Add Device modal for one-click selection.

Introduce abstract LEDClient base class with factory pattern so new
LED controller types can plug in alongside WLED. ProcessorManager is
now fully type-agnostic — all device-specific logic (health checks,
state snapshot/restore, fast send) lives behind the LEDClient interface.
- New led_client.py: LEDClient ABC, DeviceHealth, factory functions
- WLEDClient inherits LEDClient, encapsulates WLED health checks and state management
- device_type field on Device storage model (defaults to "wled")
- Rename target_type "wled" → "led" with backward-compat migration
- Frontend: "WLED" tab → "LED", device type badge, type selector in
add-device modal, device type shown in target device dropdown
- All wled_* API fields renamed to device_* for generic naming

Skip LEDs at the start/end of the strip are blacked out while the full
screen perimeter is resampled onto the remaining active LEDs using linear
interpolation. Calibration canvas tick labels show per-edge display
ranges clipped to the active LED range. Moved LED offset control from
inline overlay to a dedicated form row alongside the new skip inputs.

Skip redundant processing/DDP sends when screen is static using object
identity comparison. Add configurable standby interval to periodically
resend last frame keeping WLED in live mode. Track frames skipped,
keepalive count, and current FPS (rolling 1-second send count). Always
use DDP regardless of LED count. Compact metrics grid with label-value
rows and remove Skipped from UI display.

sums instead of 934 individual np.mean calls (~16ms -> <1ms)

Tick labels: round-number ticks (300, 900, etc.) now take priority over
edge boundary labels (288, 933). When they overlap, the boundary label
