Add plugin list links and bump version to 1.7.1

[happyloa]

Motivation

• Add a Settings link next to the plugin action buttons so site admins can jump straight to the plugin settings at admin.php?page=site-add-on-watchdog.
• Ensure the plugin author link opens in a new tab from the plugins list for better UX.
• Add a View details link to the right of the author link pointing to the plugin page on WordPress.org.
• Bump the plugin version to 1.7.1 to reflect these changes.

Description

• Added a plugin_action_links_ filter that prepends a Settings link which points to admin.php?page=site-add-on-watchdog.
• Added a plugin_row_meta filter that forces the author link to open with target="_blank" rel="noopener noreferrer" and inserts a View details link to https://wordpress.org/plugins/site-add-on-watchdog/ next to the author link.
• Updated the plugin header Version in site-add-on-watchdog.php and the Version constant in src/Version.php to 1.7.1.
• Updated readme.txt stable tag and changelog with the 1.7.1 entry describing the UI changes.

Testing

• No automated tests were run as part of this change.
• Files modified: site-add-on-watchdog.php, src/Version.php, and readme.txt were linted visually during the update.
• A commit was created with the message Add plugin action links and bump version to record the changes.
• Manual verification recommended on a WordPress install to confirm the Settings, author target, and View details links appear correctly in the Plugins list.
