feat(ui): standardize module screens + add WiFi/BLE scan-list icons

[vnxdtzip]

Proposed Changes

Brings a batch of module screens onto the standard Bruce interface and adds signal/lock icons to the scan lists, matching the look of the reworked BLE Suite / RF spectrum modules.

Screens restyled to drawMainBorderWithTitle / printSubtitle / padprintln with theme colors (getColorVariation) instead of hardcoded TFT_* constants and hand-placed cursors:

• reverseShell, rf/emit, rf/record, NRF24 nrf_info, ir/ir_read, rfid/rfid125, ethernet/HostInfo, others/timer, ir/ir_jammer, others/clicker, others/u2f, badusb_ble/ducky_typer (presenter)

Scan-list icons (opt-in, so existing menus are untouched):

• New shared helpers drawSignalBars() and drawLockIcon() in core/display.
• Option gains optional iconRssi / iconLock fields; loopOptions' drawOptions renders them right-aligned per row (both default to off).
• Applied to the WiFi lists (Connect, Deauther x2, Beacon/Target) with a lock + signal meter, and the BLE lists (Scan, Ninebot) with a signal meter. The WiFi rows drop the redundant #/dBm text now shown by the icons.

Types of Changes

UI/UX improvement + small shared helpers. No breaking changes — the icon fields are opt-in and default off, so every existing menu renders exactly as before.

Verification

Flash a device and open the restyled screens (IR Jammer, AutoClicker, Timer, U2F, RFID 125kHz, RF Record/Emit, Reverse Shell, HostInfo, nRF Info, Presenter) — each now uses the standard titled frame and theme colors. In WiFi (Connect / Deauther / Beacon) each network shows a padlock (closed = secured, open = open) and a 4-bar signal meter; in BLE (Scan / Ninebot) each device shows a signal meter.

Testing

Builds clean for m5stack-cardputer. Manually exercised on a Cardputer (ADV). No automated tests for the UI path.

Linked Issues

None. Follow-up to the BLE Suite / RF spectrum interface work.

User-Facing Change

Standardize several module screens to the Bruce frame and add signal-strength/lock icons to the WiFi and BLE scan lists.

Further Comments

Scoped to what applies on dev: the RF Scan capture-list icon (signal + saved bookmark) is intentionally left out because it depends on the "RF Scan/copy capture list" rework that isn't on dev yet — it can follow once that lands. The NRF24 CH Hopper is a separate PR (#2801).
