Extend unprotected file patterns feature to changes made via the editor and PRs

[keshane]

Feature Description

#16395 explicitly had a non-goal of applying the unprotected file pattern configuration to changes made via the editor (implicitly, merging in PRs was also a non-goal).

To make the unprotected file pattern feature be consistent, it should apply to all ways that commits can be made to a branch.

"Unprotected file patterns" implemented:

• direct commits via the CLI:

  gitea/routers/private/hook_pre_receive.go

  Line 295 in 14bb8f7

  globs := protectBranch.GetUnprotectedFilePatterns()

"Unprotected file patterns" missing:

• commits made in the UI/API (via PR merges):

  gitea/services/pull/merge.go

  Line 504 in 14bb8f7

  func IsUserAllowedToMerge(ctx context.Context, pr *issues_model.PullRequest, p access_model.Permission, user *user_model.User) (bool, error) {

• commits made in the editor:
  

  gitea/services/context/repo.go

  Line 111 in 14bb8f7

  func (r *Repository) CanCommitToBranch(ctx context.Context, doer *user_model.User) (CanCommitToBranchResults, error) {

  
  

  gitea/routers/web/repo/editor.go

  Line 47 in 14bb8f7

  func renderCommitRights(ctx *context.Context) bool {
