Add member directory tab to home navigation (#3)

* feat(healthchat): add member directory tab to home navigation

Third bottom-nav tab backed by the HealthChat API: searchable member
cards with native start-chat, approval-pending banner, retry on
failure and navigation into the native profile screens.

* fix(healthchat): stop tab back handler swallowing back presses

While a screen is pushed on top of Home, the still-composed tab
BackHandler intercepted back presses during the transition and
invisibly switched to the Chats tab. Gate it on the node's target
visibility in both the parent and Home's own backstack.

* fix(healthchat): satisfy detekt, ktlint and konsist rules

Import alias order, composable parameter order in HomeView, and konsist presenter helper shape.

* ci: pass the real repository name to the screenshot recorder

recordScreenshots.yml set GITHUB_REPOSITORY from `secrets.GITHUB_REPOSITORY`.
No such secret exists on this fork, so the expression expands to an empty
string and overrides the built-in environment variable of the same name.
recordScreenshots.sh checks it up front and exits 1 with "No repo specified",
so the workflow could never record anything here.

Use the `github.repository` context instead, which is always populated.

* test(screenshots): stop a LayoutLib teardown crash failing the shard tests

Paparazzi 2.0.0-alpha05 / LayoutLib 16.2.1 races on HandlerThread startup:
HandlerThread_Delegate.run calls Process.setThreadPriority, which throws
NoSuchMethodError for Thread.setPosixNicenessInternal and kills the
"android.bg" thread. If the test thread reaches getLooper() after that, it
gets null, BackgroundThread.ensureThreadReady() NPEs, and the static
initialiser of LatencyTracker fails. The JVM then marks that class erroneous
for the lifetime of the fork, so every later preview showing the soft
keyboard dies with NoClassDefFoundError.

LayoutLibErrorFilterStatement already swallowed the bare NoSuchMethodError,
but PaparazziLogger re-throws collected background errors from teardown()
wrapped in a MultipleFailuresException when there is more than one, and that
wrapper slipped through. A recent run reported 17 failures with zero image
comparisons failing and zero delta images written.

Unwrap the wrapper by reflection and swallow it only when every collected
cause matches the known-bug list; anything unrecognised, and anything that
cannot be decomposed, is rethrown.

Also close a hole this filter had from the start. Paparazzi runs the test as
`try { body } finally { teardown() }`, so a teardown error discards whatever
the body threw — including a genuine snapshot mismatch. renderFailureCapture
is registered inside the Paparazzi rule to record the body's exception so it
wins over any teardown error, and the filter refuses to swallow anything if
that rule is not registered. Two HorizontalFloatingToolbar previews have been
mismatching silently behind this, and may now surface as real failures.
