chore(deps): forward-port renovate updates from master to develop (#10824)

Reconciles develop to master's latest renovate values for deps bumped on the
2.7 line but never back-merged, so the develop->master 2.8 promotion (#10777)
doesn't regress them. Done as a value reconcile, not a cherry-pick: several
master commits are superseded (5 device-ui bumps, 2 ststm32 bumps), and
develop's stale archive/refs/tags/ URL form actually blocked renovate from
bumping these (the regex expects archive/<version>.zip).

GitHub Actions:
- actions/checkout v6 -> v7 (35 refs)
- actions/cache v5 -> v6
- actions/github-script v8 -> v9 (3 refs)
- actions/stale v10.2.0 -> v10.3.0

Build / platform:
- alpine 3.23 -> 3.24 (alpine.Dockerfile)
- platformio/ststm32 19.5.0 -> 19.7.0
- platformio/nordicnrf52 10.11.0 -> 10.12.0

Libraries:
- Adafruit SSD1306 2.5.16 -> 2.5.17
- SparkFun MMC5983MA v1.1.4 -> v1.1.5
- Sensirion I2C SCD30 1.0.0 -> 1.1.1
- meshtastic esp8266-oled-ssd1306 6bfd1f1 -> 2e26010

Deliberately excluded:
- meshtastic/device-ui digest: coupled to firmware protobuf/API and develop has
  diverged hard (NodeDB v25); left for a separate maintainer bump + visual check.
- libpax: develop uses the mverch67 fork (pinned by Arduino-3.x migration #9122),
  master uses dbinfrago -- a fork divergence, not a version bump; not reconciled.
- platform-native digest: develop already at 61067ac (equal to master).
