CI: tolerate a single-device DEVICE_RANGE (fix intermittent a5 job crash)

[ChaoWao]

Summary

The a5 hardware jobs (ut-a5, st-onboard-a5) and the a2a3 resource-spec step parse ${DEVICE_RANGE} with s, e = ...split('-'). When the runner's DEVICE_RANGE is a single id (no hyphen), the unpack raises ValueError: not enough values to unpack (expected 2, got 1) and the job fails before any test runs — an intermittent failure we hit repeatedly across recent PRs.

Fix: parse into a list and take first/last (s, e = p[0], p[-1]), so both "4" (→ s=e=4) and "0-7" (→ s=0, e=7) work. Applied to all 5 split sites.

Testing

• Logic verified locally: "4"→4, "0-7"→0,1,…,7, "0"→0
• ci.yml YAML parses; pre-commit clean
