Add password reset mechanism (Issue #1)

- Added reset_token and reset_token_expiry fields to User model
- Implemented generate_reset_token(), verify_reset_token(), and clear_reset_token() methods
- Created password reset request form (/password-reset-request)
- Created password reset form (/password-reset/<token>)
- Added "Forgot password?" link to login page
- Reset tokens expire after 1 hour for security
- Created migration script to add new database columns
- Reset links are logged (would be emailed in production)

+# Template Creation Prompt for AI
+
+This document describes the data structures, helper functions, and conventions an AI needs to create or modify HTML templates for this social media archive system.
+
+## Data Structures Available
+
+### Post Data (when rendering posts)
+- **Available in all post templates (card, list, detail):**
+  - platform: string (e.g., "reddit", "hackernews")
+  - id: string (unique post identifier)
+  - title: string
+  - author: string
+  - timestamp: integer (unix timestamp)
+  - score: integer (up/down vote score)
+  - replies: integer (number of comments)
+  - url: string (original post URL)
+  - content: string (optional post body text)
+  - source: string (optional subreddit/community)
+  - tags: array of strings (optional tags/flair)
+  - meta: object (optional platform-specific metadata)
+  - comments: array (optional nested comment tree - only in detail templates)
+  - post_url: string (generated: "{uuid}.html" - for local linking to detail pages)
+
+### Comment Data (when rendering comments)
+- **Available in comment templates:**
+  - uuid: string (unique comment identifier)
+  - id: string (platform-specific identifier)
+  - author: string (comment author username)
+  - content: string (comment text)
+  - timestamp: integer (unix timestamp)
+  - score: integer (comment score)
+  - platform: string
+  - depth: integer (nesting level)
+  - children: array (nested replies)
+  - children_section: string (pre-rendered HTML of nested children)
+
+## Template Engine: Jinja2
+
+Templates use Jinja2 syntax (`{{ }}` for variables, `{% %}` for control flow).
+
+### Important Filters:
+- `|safe`: Mark content as safe HTML (for already-escaped content)
+- Example: `{{ renderMarkdown(content)|safe }}`
+
+### Available Control Structures:
+- `{% if variable %}...{% endif %}`
+- `{% for item in array %}...{% endfor %}`
+- `{% set variable = value %}` (create local variables)
+
+## Helper Functions Available
+
+Call these in templates using `{{ function(arg) }}`:
+
+### Time/Date Formatting:
+- `formatTime(timestamp)` -> "HH:MM"
+- `formatTimeAgo(timestamp)` -> "2 hours ago"
+- `formatDateTime(timestamp)` -> "January 15, 2024 at 14:30"
+
+### Text Processing:
+- `truncate(text, max_length)` -> truncated string with "..."
+- `escapeHtml(text)` -> HTML-escaped version
+
+### Content Rendering:
+- `renderMarkdown(text)` -> Basic HTML from markdown (returns already-escaped HTML)
+
+## Template Types
+
+### Card Template (for index/listing pages)
+- Used for summary view of posts
+- Links should use `post_url` to point to local detail pages
+- Keep concise - truncated content, basic info
+
+### List Template (compact listing)
+- Even more compact than cards
+- Vote scores, basic metadata, title link
+
+### Detail Template (full post view)
+- Full content, meta information
+- Source link uses `url` (external)
+- Must include `{{comments_section|safe}}` for rendered comments
+
+### Comment Template (nested comments)
+- Recursive rendering with depth styling
+- Children rendered as flattened HTML in `children_section`
+
+## Convenience Data Added by System
+
+In `generate_html.py`, `post_url` is added to each post before rendering: `{post['uuid']}.html`
+
+This allows templates to link to local detail pages instead of external Reddit.
+
+## CSS Classes Convention
+
+Templates use semantic CSS classes:
+- Post cards: `.post-card`, `.post-header`, `.post-meta`, etc.
+- Comments: `.comment`, `.comment-header`, `.comment-body`, etc.
+- Platform: `.platform-{platform}` for platform-specific styling
+
+## Examples
+
+### Conditional Rendering:
+```
+{% if content %}
+  <p class="content">{{ renderMarkdown(content)|safe }}</p>
+{% endif %}
+```
+
+### Looping Tags:
+```
+{% for tag in tags if tag %}
+  <span class="tag">{{ tag }}</span>
+{% endfor %}
+```
+
+### Styling by Depth (comments):
+```
+<div class="comment" style="margin-left: {{depth * 20}}px">
+```
+
+When creating new templates, follow these patterns and use the available data and helper functions appropriately.
