test(e2e): use neutral iOS slot simulators

[mikehardy]

Summary

• Use neutral iOS slot simulator names (RN E2E iOS slot-N) shared by React Native e2e harnesses, with slots 0–7 available.
• Patch Detox allocation for neutral slots to reuse the exact assigned base simulator or fail with actionable ownership guidance when that base is already registry-taken. Detox never escapes to a -Detox clone for these slots; Mellifera/manual slot assignment owns exclusivity.
• Keep setup create/reuse-only, check/release exact-name scoped, Android slot support intact, and legacy RNFB E2E iOS slot-N removal an explicit operator migration.
• Keep the configured slot count and slot bounds consistent across environment export, device provisioning, resource checks, and release.

Test plan

• Root install applies the rewritten detox@20.51.0 patch; focused slot/device contract tests pass 68/68; JS lint passes.
• Live area-focused iOS proof on slot 7 passes 42 tests using the pre-existing exact base UDID, with no simulator create operation and no -Detox device produced.
• Scoped release leaves slot 7 and owned services clear; slot 3 is untouched.
• Fresh independent frozen review and OKF consistency scan pass with no findings.

revisiting the -Detox sim/emu device clone naming thing - unhappy with "force Detox clone device" direction and rather want to invert "only ever use base device" so detox fails if base device is taken vs silently consuming disk with clone-on-demand device creation

better - this is the one that works best for me in a multi-slotted local e2e env
