v6 T3a: ZED-F9P + generic SOT-23-5 LDO symbols added to Drogheda-sym

ZED-F9P: all 54 pins, numbers 1-54 complete and unique, transcribed from the u-blox
datasheet Table 11 (ZED-F9P-15B_DataSheet_UBX-23009090). Left column = power/RF/antenna
(17), right = interfaces/control/status (16), bottom = the 21 reserved pins. Body 55.88 x
50.8 mm. LCSC C5120257 carried as a property.

FINDING that changes Block N: the ZED-F9P HAS hardware status outputs - RTK_STAT (pin 20)
and GEOFENCE_STAT (pin 19). RTK_STAT: 0 = RTK fixed, blinking = receiving and using
corrections, 1 = no corrections. That is a HARDWARE answer to the question the June and
10-Ago RCAs could not answer. Wire RTK_STAT to PC3. (Earlier note implying only the UM980
had such pins was wrong.) ANT_OFF (pin 5) also exists.

LDO_SOT23-5: generic AP2112K / TPS7A20 pinout (1=VIN 2=GND 3=EN 4=NC/NR 5=VOUT) so U21
can be any SOT-23-5 low-noise LDO without a symbol change.

OPEN - blocks the PCB side of T3, not the schematic:
 * No ZED-F9P FOOTPRINT exists. Not in the project libs, not derivable from the datasheet
   (no land pattern) and the integration manual's drawings do not survive PDF text
   extraction. EasyEDA/LCSC is blocked by the egress allowlist from here.
   Fix: run locally -> pip install easyeda2kicad && easyeda2kicad --full --lcsc_id=C5120257
 * PRE-FAB CHECK: confirm the -04B datasheet carries the SAME pin assignment as the -15B.
