Add ActiveStatusCell/PassiveStatusCell wrappers in the scanners common
module so the five per-scanner status.rs files reduce to a single static;
replace parse_parameter_bool/int/string with one generic parse_parameter
over FromStr; extract the shared LIMIT/OFFSET paging clause into
db::apply_paging; and drop a no-op for-loop in the ARP sender.

The ARP and SNMP scanners reported every online sighting, so a device
seen on multiple IPs or via duplicate ARP replies was counted more than
once. Fold the dedup into ActiveStatus::record_scan, which now takes the
device slice and reports the number of distinct MAC addresses.

The five scanners (ARP, SNMP, mDNS, SSDP, DHCP) duplicated their
persist-and-notify pipeline, device enrichment, and status state
machines across same-family files. Extract the shared logic so a change
lands in one place instead of three to five.
- scanners/common/pipeline.rs: single record_sighting() persist+notify
path, replacing the per-scanner match blocks. ARP/SNMP now use the
same merge rules as the passive scanners (keep a stored hostname,
never overwrite a known IP with an empty one).
- scanners/common/enrichment.rs: build_device() for vendor/device-type
lookup with the privacy-MAC service fallback.
- scanners/common/{active,passive}_status.rs: the two status state
machines plus their tests, written once. Each scanner status.rs is now
a thin wrapper over its own static.
- utils/network::format_mac(): replaces three identical copies.
- web_server/scanner_status.rs: Active/Passive response types and two
handler helpers, replacing five near-identical structs+handlers. JSON
field names are unchanged so the frontend is unaffected; only OpenAPI
schema names change.
27 files changed, ~900 lines net removed. Build, clippy and all 113
tests (4 new) pass.
