fix: Check storage before setting default signature on install/update

Fixed getting company name for custom companies + other minor fixes

- Fix getting company name for different scenarios
- feature: Update LinkedIn signature with profile name
- Allow separate signatures for messages and connection requests
- Improved popup UI with multiple changes

- Fix: Connection note used to get reset when the focus was lost
- Feature: Added the extension icon to toggle the signature from the message form itself

Latest Update: Removed unused "tabs" permission

Now, personalize your experience by toggling signatures in connection notes and messages individually. Also, the uninstall survey fills in (doesn't submit) non-personal technical details automatically for improved support—no need to find and fill in the data yourself.

Add signatures to the custom note box while sending someone a request to connect.

Multiple changes since v2.0.0

- Added support for icon change in dark mode.
- Changed the name to SignatureSync due to a legal notice from the original professional website for which I created this extension
- Made the extension compatible with manifest V3

The extension now works again with the new LinkedIn UI. Also disabled the slider checkbox to enable or disable the signature, you can still enable/disable it from the browser action popup.

LinkedIn changed the class names on their message forms so enable/disable switch was not showing. Fixed it.

fixed a bug where in case when localstorage was empty, content script was breaking

Added a switch to enable/disable LinkedIn messages signatures via the UI and no need to click the extension icon.

1. Signature will not auto append on page load but only when you click on the message box.
2. If you delete it, it will also not be added again which was annoying.
3. After the signature is added, the typing caret will automatically move to the beginning of the message so you can start typing your message right away.
