For high voltage servos like these, I see that it is rated for 7.5-9.2A of stall current. Is the wire and headers that come with the servo actually rated for such a high current? For example, I would expect the dupont headers to be rated for 3A, while the 22-24AWG wires (I can't tell if it's 22 or 24) to be 3.5-7A.
I would worry about the duponts, especially if they are the Chinese design. THey will likely work in the beginning but will start to provide contact loss as you run more and if you plug and unplug a number of times.
Just a note, if the connector pins are gold plated use gold male headers. However if they are tin use tin headers. Never mix tin with gold.
The wire should not be a large concern because or the short runs.
1 foot of #24 = 0.025 ohms.
I do t think any of the breadboards are suitable for high currents anyway
You should not be using servos in a stalled state for any length of time and normal currents are much lower than the stall current so it's not really much of a problem. Problems with connectors and wiring are mainly due to heating.

Not for continuous use at stall, no, I doubt any hobby servo is rated for continuous stall - they tend to overheat and die if you try. Typically RC hardware is deliberately overrated
and is likely to fail over time - cheapness and lightness is seen as much more desirable
for RC models which are not going to see operation for long periods nor for a long
total operating time.
For instance its common for RC connections to use silicone insulated wire as this can
withstand 200C or so when the wiring is over-driven. The connectors are only gold-plated
because otherwise they would oxidize badly through overheating. Silicone insulated
wire means less weight of copper is needed and the aircraft can thus be lighter - the fact
10% of the battery power might be wasted in the wiring is something you then have to
accept.
