Route the remaining WP.com clients through WpComApiClientProvider

[adalpari]

#TL:DR

Follow-up to #23295: the last two WP.com clients that bypassed
WpComApiClientProvider now go through it, so they get the locale provider and
the redacting error logger too.

Description

Follow-up to #23295 (wordpress-rs 0.8.0 migration). That PR added two things
to WpComApiClientProvider:

• a WpComLanguageProvider, so WP.com responses come back localized (0.8.0 moved
  the locale query parameter off the endpoint params and onto the client), and
• a WpRequestErrorLogger using the library's default redaction policy, replacing
  the removed WpRequestResult.toLogErrorString().

Review of that PR flagged that two callers construct WpComApiClient directly
rather than going through the provider, so they got neither:

• DataViewViewModel (and therefore its subclasses ApplicationPasswordsViewModel,
  SubscribersViewModel, TermsViewModel)
• AddSubscribersViewModel

Their WP.com responses were unlocalized, and their request failures were logged
without redaction.

Why they bypassed the provider

Both need the network-request tracking interceptor (the Chucker-based inspector),
and the provider's client didn't support interceptors — it built its own OkHttp
client with the shared wp-rs timeouts.

So rather than drop the interceptor, this PR gives the provider an optional
interceptors parameter that installs them on that OkHttp client:

fun getWpComApiClient(
    accessToken: String,
    interceptors: List<Interceptor> = emptyList(),
): WpComApiClient

Existing callers are unaffected (they pass nothing). The two former bypassers keep
request inspection and additionally gain the shared timeouts, the error logger and
the language provider.

The interceptor stays opt-in rather than being injected into the provider itself,
so this doesn't silently enable network-request tracking for every other WP.com
consumer (stats, domains, support).

Knock-on change

DataViewViewModel now takes WpComApiClientProvider in place of the raw
WpNetworkAvailabilityProvider it only used to build the client; its three
subclasses pass it through. Tests updated accordingly.

Testing instructions

1. Build and static analysis.

• ./gradlew assembleJetpackDebug succeeds
• ./gradlew detekt passes

2. Unit tests.

• DataViewViewModelTest, TermsViewModelTest, SubscribersViewModelTest,
  ApplicationPasswordsViewModelTest pass

3. Exercise the affected screens on a WP.com site: Subscribers (list, detail, add),
   Application Passwords, and Taxonomies/Terms.

• All still load, paginate and search as before

4. With the device language set to a non-English locale.

• Server-rendered strings on those screens come back localized, confirming the
  client-level locale is now being sent

5. Enable the network-request tracker (App Settings → debug tools) and use those
   screens.

• Requests are still captured, confirming the interceptor survived the move
