chore(adr-115): expand witness bundle manifest — Matter + release + blueprints + Lovelace + ops

The witness-bundle generator's `ADR_FILES` array was snapshotted at
P10 (commit a4f56d2f1). Since then we've shipped:
- 4 Matter source files (P7+P8a: mod.rs, clusters.rs, bridge.rs,
   commissioning.rs)
- 4 ops/docs files (v0.7.0 release notes, benchmarks.md,
   validate-esp32-mqtt.sh, validate-ha-blueprints.py)
- 9 blueprint files (README + 8 YAMLs under examples/ha-blueprints/)
- 4 Lovelace files (README + 3 dashboard YAMLs)
- Also fixed a typo where the manifest pointed at
   `src/Cargo.toml` instead of the crate-level `Cargo.toml`.

After this commit the witness bundle's `manifest/source-hashes.txt`
covers **55 files** (was 28) — full source surface that ships with
v0.7.0. Bundle still self-verifies end-to-end via `bash VERIFY.sh`.

Local regen + verify on HEAD cb3ea9fbd:
  bash scripts/witness-adr-115.sh
  cd dist/witness-bundle-ADR115-*/ && bash VERIFY.sh
  → ADR-115 witness bundle: VERIFIED ✓
