Fix 400 errors on views and repository branches endpoints

[Copilot]

Two endpoints return 400 errors after upgrade to 2.16.35/36:

• /api/project/{id}/views: gorp: no fields [hidden type filter sort_column sort_reverse] in type View
• /api/project/{id}/repositories/{id}/branches: chdir /tmp/semaphore/project_1: no such file or directory

Changes

View struct (db/View.go)

• Added optional nullable fields to handle extra database columns that may exist in some installations (pro version, manual migrations):

  Hidden       *bool   `db:"hidden" json:"hidden,omitempty"`
  Type         *string `db:"type" json:"type,omitempty"`
  Filter       *string `db:"filter" json:"filter,omitempty"`
  SortColumn   *string `db:"sort_column" json:"sort_column,omitempty"`
  SortReverse  *bool   `db:"sort_reverse" json:"sort_reverse,omitempty"`

  Allows gorp to map these columns when present without breaking standard installations.

Git client (db_lib/CmdGitClient.go)

• Create project tmp directory if it doesn't exist before executing git commands
• Log errors on directory creation failure for debugging
• Commands like ls-remote don't need a local repo but still require a working directory to execute

<issue_title>Problem: Multiple APIs Return 400 since Update to 2.16.35/2.16.36</issue_title>
<issue_description>### Issue

For example the Endpoint /api/project/1/views on my Instance returns with Error 400 since the latest update, wich makes the GUI mostly unusable.

/api/project/1/views 400
