cy8ckit_062_wifi_bt: blinky samples fail to run

[recalci]

Describe the bug

The samples/basic/blinky compiles successfully, but after west flash, the board has no LED blinking and zero UART output.

Regression

• This is a regression.

Steps to reproduce

1. west build -p always -b cy8ckit_062_wifi_bt/cy8c6247/m0 samples/basic/blinky
2. west flash

Relevant log output

Impact

Major – Severely degrades functionality; workaround is difficult or unavailable.

Environment

• OS: windows 10
• Toolchain: Zephyr SDK
• Version: v4.3.0

Additional Context

1. Firmware compiled via Infineon ModusToolbox (same LED/UART logic) runs normally on the board → flashing tool and hardware are functional.
2. The Zephyr firmware works only when loaded via west debug (followed by continue in GDB); this issue matches Some problems when run zephyr on PSoC63 (PSoC6 BLE Pioneer Kit) #83466.
3. Replacing Zephyr's k_msleep(...) with Infineon's Cy_SysLib_Delay(...) or Cy_SysLib_Rtos_Delay(...) enables normal operation in west debug mode; the while loop runs without delay otherwise.
4. The sample works normally on the cy8ckit_062s2_ai with no additional modifications required.
