Format BSSID MAC addresses with leading zeros for consistency with Android (#4095)
## Summary
BSSID sensor reported MAC addresses without leading zeros (e.g.,
`18:e8:29:a7:e9:b`), inconsistent with Android companion app and
standard MAC address notation. This breaks cross-platform room presence
tracking.

**Changes:**
- Added `String.formattedBSSID` extension that pads hex octets to 2
characters
- Applied formatting to BSSID sensor state in `ConnectivitySensor`
- Added test coverage for formatting edge cases

```swift
// Before: "18:e8:29:a7:e9:b"
// After:  "18:e8:29:a7:e9:0b"
sensor.State = bssid.formattedBSSID
```

## Screenshots
N/A - Sensor value formatting change only

## Any other notes
**Breaking change:** Users with BSSID-based automations must update to
the new zero-padded format. This aligns iOS with Android, standard MAC
notation, and network management tools like UniFi.

> **Describe the bug**
> The BSSID sensor reports access point mac address with leading zeros
omitted
> example:
> 
> ```
> 18:e8:29:a7:e9:b
> ```
> The last number is 0x0b
> 
> An adroid device connected the the same access point returns 
> 
> ```
> 18:e8:29:a7:e9:0b
> ```
> **To Reproduce**
> You need to have an access point with mac bytes lower then 0x10
> 
> **Expected behavior**
> Having same BSSID representation than reported by Android App
companion

> **Additional context**
> I'm using BSSID to track room presence based on connected AP. I'm
trying to share BSSID --> access point for all household mobile.
> 
> I'd prefer the version with leading 0 witch is aligned with Unify
management tool.

> We're just slurping the value we read from the system, so we'd need to
sanitize the input to change it. It would also be a breaking change for
modifying what values are sent up, which is less-than-ideal since users
get auto-updated in the apps. I'm not sure there's a great path forward
for resolving this.</body></comment_new>
