fix(samples): Use float literal for session-replay sample rate

[runningcode]

📜 Description

The Android sample app set the session replay sample rate as an integer literal:

<meta-data
    android:name="io.sentry.session-replay.session-sample-rate"
    android:value="1" />

aapt stores "1" as an integer. ManifestMetadataReader.readDouble reads the value via Bundle.getFloat(key, -1), which does not coerce an int-typed value — it returns the default and the Android framework logs a warning like:

W/Bundle: Key io.sentry.session-replay.session-sample-rate expected Float but value was a java.lang.Integer.  The default value -1 was returned.

The reader then falls back to getInt, so the resulting value is still correct (1.0), but a framework warning is logged on every startup. Using the float literal "1.0" stores the value as a float, so getFloat succeeds on the first read and no warning is logged. This also matches the other sample-rate entries in the same manifest, which already use 1.0.

📝 Checklist

• I added GH Issue ID & Linear ID
• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.
