`@lib/app/modules/manage_task_champion_creds/controllers/manage_task_champion_creds_controller.dart`:
- Line 14: Update the test references in taskchampion_test.dart to use the
renamed controller field and storage key: replace usages of
ccsyncBackendUrlController with syncBackendUrlController and update any storage
key string ccsyncBackendUrl to syncBackendUrl so the tests reference the new
TextEditingController field name (syncBackendUrlController) in
ManageTaskChampionCredsController.

In `@lib/app/utils/language/bengali_sentences.dart`:
- Around line 5-16: The Bengali localization still contains literal "CCSync"
text inside the sync-related getters (syncLoginInstruction, syncEasySyncTitle,
syncOpenButton, syncIntro, syncSelfHosted); update those string values to use
the renamed sync product text consistent with other locales (replace "CCSync"
with the canonical sync name used elsewhere, e.g., "TaskChampion Sync" or the
project's agreed term) so all locales match the renamed getters.

In `@lib/app/utils/language/english_sentences.dart`:
- Line 227: The getter syncCredentials currently returns the string 'CCync
credentials' with a typo; update the return value of the syncCredentials getter
in english_sentences.dart to the correct label 'Sync credentials' (keeping the
getter name syncCredentials unchanged) so it aligns with the PR's "Sync"
terminology.

In `@lib/app/utils/language/hindi_sentences.dart`:
- Around line 5-16: Several Hindi strings still use "CCSync" while other keys
like syncCredentials and syncBackendUrl use "Sync"; update the strings for
syncLoginInstruction, syncEasySyncTitle, syncOpenButton, syncIntro, and
syncSelfHosted to consistently use "Sync" (or the chosen unified product name)
instead of "CCSync" so translations match other files and keys; ensure the same
wording is applied as in Marathi and other locales to keep UX consistent.

In `@lib/app/utils/language/marathi_sentences.dart`:
- Around line 5-17: Update the Marathi strings to consistently use the new
"Sync" naming instead of "CCSync": change the values for syncLoginInstruction,
syncEasySyncTitle, syncOpenButton, syncIntro, and syncSelfHosted to replace
"CCSync" with "Sync" (or the localized equivalent used by syncCredentials and
syncBackendUrl) so all sync-related keys (including syncCredentials and
syncBackendUrl) use the same term across the locale.

In `@lib/app/utils/language/urdu_sentences.dart`:
- Line 229: The getter syncCredentials currently returns the string with a typo
and legacy "CCSync" mention; update the return value of String get
syncCredentials to use the new naming convention by replacing 'CCync اسناد' with
'Sync اسناد' so it no longer contains the incorrect/legacy "CCSync" text.

In `@lib/rust_bridge/frb_generated.dart`:
- Line 68: The generated Dart constant codegenVersion in frb_generated.dart is
2.12.0 but the Rust side is still at 2.11.1, so update the Rust crate
dependencies in Cargo.toml (flutter_rust_bridge, flutter_rust_bridge_macros,
flutter_rust_bridge_codegen) to match "=2.12.0" and then re-run the bridge
generator (flutter_rust_bridge_codegen generate) to regenerate
rust/src/frb_generated.rs so the version emitted by the Rust bridge matches the
Dart code and RustLib.init() with forceSameCodegenVersion will succeed.

Inline comments:
In `@test/utils/taskchampion/taskchampion_test.dart`:
- Around line 26-37: The test currently mocks SharedPreferences but
loadCredentials() uses file-based CredentialsStorage APIs, so replace the
SharedPreferences setup with direct stubs/mocks for
CredentialsStorage.getApiUrl(), CredentialsStorage.getClientId(), and
CredentialsStorage.getEncryptionSecret() (or create the expected credential
files under the test temp profile path) so that
ManageTaskChampionCredsController.loadCredentials() reads the expected values;
locate and update the test to mock those static methods (or write the
backend_url_tc, client_id_tc, encryption_secret_tc files) and then assert
controller.syncBackendUrlController.text, clientIdController.text, and
encryptionSecretController.text as before.
- Around line 40-51: The test currently asserts SharedPreferences writes but
saveCredentials() actually writes files via CredentialsStorage and calls
profilesWidget.setTaskcCreds(); update the test to either (A) mock the file
system or CredentialsStorage and assert that CredentialsStorage.write (or the
concrete method used) and profilesWidget.setTaskcCreds() are invoked with the
expected values and keys ('taskc_client_secret', 'taskc_client_id',
'backend_url_tc'), or (B) remove the SharedPreferences assertions and instead
read from the profile file created by CredentialsStorage to assert the stored
values; locate saveCredentials(), CredentialsStorage, and
profilesWidget.setTaskcCreds() to apply the change.

Nitpick comments:
In `@test/utils/language/french_sentences_test.dart`:
- Around line 7-180: Add two assertions for the new French sync getters: ensure
the test includes expect(french.syncBackendUrl, '<expected French string>') and
expect(french.syncClientId, '<expected French string>'); locate the canonical
French strings in the French localization file (the same resource that defines
the other french.* getters) and use those exact values so the test verifies the
newly added overrides for syncBackendUrl and syncClientId.
