fix(gitea-prs): correct reference drift against gitea-mcp v1.7.0

The reference files were last verified against v1.3.0 -- references/sources.md
still said so. PR #106 re-verified the write side only, so three defects had
accumulated on the read/review side. All three reproduced against the deployed
server before being fixed; get_gitea_mcp_server_version reports v1.7.0.

- reviews.md forbade review_comments on the "get" response and directed callers
  to review_scomments, which does not exist. The upstream slim.go typo was
  corrected; a live pull_request_read on PR #106 returns "review_comments":1 and
  no review_scomments key. review_comments is an integer count, not comment
  objects -- distinct from the get_review_comments method. Also fixed in
  pull-requests.md's response-shape list.
- pull_request_review_write grants seven methods; only four were documented.
  reply_comment, resolve_thread, unresolve_thread and the comment_id parameter
  had zero mentions anywhere in the skill. Documented from the schema, in a
  Comment threads section kept outside the numbered review state machine --
  they are not lifecycle states.
- review_id was documented as required for get_review_comments. It is optional;
  omitting it lists every inline comment on the PR. Confirmed behaviourally:
  get_review without it errors, get_review_comments without it returns [].

sources.md now records v1.7.0 as the last-verified version, so the next reader
knows what these files were checked against.

+Parameter signatures below are cross-checked live against the deployed gitea-mcp server tool schemas at authoring time — not copied verbatim from the plugin's research doc for this domain, which has a known history of drifting from the deployed server (e.g. a prior `type` parameter that no longer exists on `list_issues`). These files were last verified against gitea-mcp **v1.7.0**, as reported by `get_gitea_mcp_server_version`. Re-verify via `ToolSearch` before trusting this file if the deployed version differs — drift has bitten this skill in both directions, adding methods it does not list and fixing quirks it still warns about.
